EleMints User Guide

This User Guide is meant to get you more familiar with EleMints and how to use it. EleMints has a lot of features to help you, be it in your chemistry class, in the professional field, or even for every day reference to settle curiosity.

When EleMints launches, you are presented with a Tab Bar at the bottom of the screen. This Tab Bar allows you to jump to the different sections of the application. The sections are labeled as follows: Table, Plot Graph, Elements, Articles, and Tools.

The several tabs located at the bottom of the screen.

There is also a Properties Panel available when more information about an element is requested, and a variety of customizable settings in the Settings App.

Periodic Table Tab

The Table Tab presents you with a Periodic Table showing all the elements. If you tap an Element's Tile, the More Info Popup is displayed showing a variety of information. Additionally, information about the selected element is displayed in the Element Legend to the left of the table.

Element Legend and More Info Popup.

Note: The More Info Popup can be hidden in the Settings App.

To scan across the Values of each element, simply tap and hold anywhere and drag your finger across the screen. If a Value is not available for an element, that element will be grayed out, and will present the words No Data instead of a valid Value. Additionally, while you drag across the table, elements having the same group or period will be slightly shaded.

Note: You can only scan across the elements if you are completely zoomed out. Otherwise, you will scroll across the Table instead.

If you want to see more information about the element directly on an Element's Tile, simply perform a Pinch gesture outwards to zoom in or inwards to zoom out. While zoomed, you can scroll across the table, and see the information that is normally presented inside of the Element Legend.

An Element Tile zoomed at different amounts.

Note: Double Tapping an element will zoom you all the way in.

When completely zoomed in, the state symbol is shown to the right, while the crystal structure is shown to the left.

Crystal and State Symbols.

To get even more information about an element, tap the blue button of the More Info Popup when it is displayed. This will open the Properties Panel, where you can get a wealth of information on each element.

Note: If you chose to hide the popup, simply tap the Element Legend.

The Periodic Table can also be colored in a variety of ways to show trends across periods and down groups. To do so, tap the Color Wheel located at the bottom-right portion of the screen to open the Configuration Panel.

Configuration Panel for the Table Tab.

This Configuration Panel allows you to choose a coloring Mode for the table. Choose the Mode by dragging your finger on the Mode Picker. The Mode will then be displayed on the top portion of the screen. A slider allows you to distribute the Values differently so certain values become more apparent on the Table. Leaving the slider in the center will not alter the Values in any way.

Currently supported Modes are:

Classification
Electronegativity
Melting Point
Boiling Point
Physical State
Density
Specific Heat
Crystal Structure
Empirical Atomic Radius
Calculated Atomic Radius
Covalent Radius
Van der Waals Radius
Triple Bond Covalent Radius
Metallic Radius
Atomic Weight
Period
Group
Block
Number of Protons
Number of Neutrons
Number of Nucleons
Proton : Neutron Ratio

Once you are done configuring the Table, tap the Color Wheel again to close the Configuration Panel. Element Tiles will now be colored depending on the Values of the Mode selected. If the Mode represents Numeric Values, then the tiles will be shaded according to the Value's relativity to the minimum and maximum of the selected Mode.

Note: You can change the color of the shading in the Settings App.

If the orientation of the Periodic Table displeases you, simply slide two fingers across the screen while zoomed out to flip the table.

Plot Graph Analyzer Tab

The Plot Graph Tab allows you to graph properties of the elements to see how they change across a period or down a group.

The horizontal axis presents all the elements ordered by atomic number, and grouped up either by period or by group. The vertical axis represents the values of the current Mode.

The slider at the top can be used to control the brightness of the graph. The Button located at the top-right portion of the screen can be used to enter the Configuration Mode for the graph.

Note: The Button will only be available in the portrait orientation. If you are in a landscape orientation, please rotate the device upright into the portrait orientation.

Configuration Mode for the Plot Graph Tab.

This Configuration Mode allows you to choose a Mode for the graph. Choose the Mode by dragging your finger on the Mode Picker. The Mode will then be displayed on the top portion of the screen. A slider allows you to distribute the Values differently so they are more apparent on the Graph. Leaving the slider in the center will not alter the Values in any way, and by dragging it, you can see how the distribution of Values changes with the dots shown right above it.

The Physical State Mode, however, uses this value to show the state of an element at a certain temperature, indicated by the position of the slider. The default value for this mode is at 288.15 K, or 15°C. Additionally, the dot view will show the present state of the elements at that temperature. Blue indicates a Solid, White a Liquid, and Red a Gas.

To select an element, simply tap the screen to show a More Info Popup, and tap it's blue button to open the Properties Panel. To get more control over your selection, tap, hold and drag across the screen to position the More Info Popup appropriately.

This becomes even more useful for the Physical State Mode, where the position you drag your finger will indicate whether the element is solid, liquid or gas. Under the Blue Line indicates a Solid, between the Red and the Blue Lines a Liquid, and above the Red Line a Gas.

Element Listing Tab

The Elements Tab allows you to order the elements in a variety of different ways to enable you to find exactly what you are looking for. Simply tap a Property to bring up a list of all the Elements ordered by that Property. You can use the Index to the right to jump to a specific Value. Simply tap an element to be brought to the Properties Panel.

Note: The Element Tiles to the left of each element are filled relative to the maximum value of that Property.

Articles Tab

The Articles Tab contains all the documentation on EleMints, along with hundreds of online articles on the elements and chemistry in a more general sense. Additionally, in the About section, you can easily contact us if you would like more articles added, or would like to suggest more properties or features to add.

Note: It is strongly recommended to be connected to a WiFi network while using the Articles Tab, as loading each article may take a while on a cellular connection.

Tools Tab

The Tools Tab easily and effortlessly calculates Molar Masses and the percentage by mass of each element in the sample. Simply type the formula, and the molar mass will automatically be calculated. Coefficients will automatically be set to subscript if necessary. Additionally, multiple substances may be added by separating each one with a space or +.

Note: Elements are case sensitive. Cu (Copper) will be interpreted differentially than CU (Carbon and Uranium).

Properties Panel

The Properties Panel lists all the supported Properties for each element. To get more information about a type of Property, simply tap it to get a small Definition. The Pie Chart to the right is shaded relative to the maximum value of that Property.

Note: The Definitions, Pie Charts, and Simple Properties can all be hidden in the Settings App.

Tapping on either of the four directional buttons located at the top will progress you to the next or previous Element, ordered by Period and Group.

If you tap Electron Shell Diagram row, you will be presented with an electron diagram. The nucleus shows the proportion between Protons (dark) and Neutrons (light). The shells around it are colored by energy level. To enable sub shells to be shown, tap the Value Label under the "electron configuration" text. Sub shells are ordered by the amount of energy they contain. To show all the sub shells of a specific shell, simply drag your finger around the nucleus to highlight all the electrons of that shell. Tap the Show All Properties Button to return.

Note: The Landscape version of the electron diagram will only show the seven major shells.

If you would like even more information, you could refer to the Links section, where you could open the Wikipedia Article or WebElements Article for that element.
