The Glossary gives you definitions of the most used tools in chemistry as well as some knowledge data. On the left side of the windows you can see the tree of items. On top, there are chemical terms, below that there is a second tree of labaratory-tools.
On the top of the widget you can see a searchbar. If you type in the bar the trees will be adjusted immediately. The small button left of the searchbar will clear it.
The dialog allows you to plot some information about elements. The X-axis represents a range of elements (from one number to a higher number). You set this range using the First Element and Last Element fields on the dialog. The display does not change until you click on the button.
Kalzium can plot some data about a range of elements.
The enables the user to solve chemical equations. This is an example:
aH2O + bCO2 -> cH2CO3
The computed equation will be displayed on the right side of the window. As you can see in the first example you can also define the value of one or more coefficients. The other coefficients will be ajusted. Furthermore, it is possible to use brackets around elements or electronic charges as shown in the last two examples.
Kalzium can solve chemical equations
The Overview tab is the first one and it shows you an overview of the element the mouse is over.
Element is essential to all species
Element is essential for at least one species
Biological function is proposed
Element is essential for humans
Element is probably essential for humans
The Calculate tab is the second in the sidebar. It alows you to calculate molecules weights.
You are first presented with the following:
The calculator when it is started.
In this example, the mass of ethyl alcohol (regular alcohol) H3CH2OH will be calculated. For this, simply enter the formula in the lineedit and either press enter or click on the -button. The result of the calculation will be displayed below.
As you can see you will get several answers. For one, on top of the widget you will see the empirical formula, H6C1O1. At the bottom of the widget there is a list of elements and their abundance in the entered molecule and finally the mass of the molecule.
The tooltip of the widget will show you the relativ masses of the elements in the molecule. In this example, the six hydrogen have only 17.76% of the mass of the molecule.
The result of the calculation.
The Timeline feature allows you to explore the elements of the set time period. This is great for getting a feel for how the PSE evolved over time, as more and more elements were discovered. If you move the slider you will notice that some elements disappear if you move it to the left and reappear if you move it to the right. Furthermore the number will change constantly.
The number represents the date you are looking at. If you move the slider to e.g. 1891 you will only see the elements which where known in the year 1891.
You will notice that some elements are not even shown in the current year. This is because some of the elements have not been discovered yet but are predicted to exist.
The PSE back in time (elements known in 1891)
With the State of Matter function, you can choose a temperature and view the state of each element at that temperature. You can easily visualize how many elements and what elements are, for example, solid at a given temperature. So you can learn that almost all are solid at very low temperatures and that most are liquid or even vaporous at high temperatures.
Kalzium can show you which elements are solid/liquid/vaporous at a given temperature.
The Show/Hide Legend action allows you to display the legend for the scheme you are in (Groups, Blocks, Acid Behavior). The legend is displayed by default but if you hide it, it will stay hidden until you choose to show it. Kalzium will keep this setting in its configuration file, so that the next time you run it, the setting will be as you left it.
