The Periodic Table

Select the elements you wish to work with in the PERIODIC TABLE window by clicking individual element buttons or labeled buttons that select categories of elements.
To make a graph, in the GRAPH window, select the property you wish to plot on the x–axis from the X menu and the property you wish to plot on the y–axis from the Y menu. The graph appears automatically.

To use the sorting table, in the TABLE window, select the properties that interest you from the TABLE FIELDS menu. You can select up to 3 properties. Click a column header to sort the information by the data in that column.
Detailed information about each of the windows and the options and features they contain is found below.

PERIODIC TABLE Window
The PERIODIC TABLE window, located in the upper left corner of the browser window, is the heart of the applet. It is illustrated in Figure 2.1. Only data for the elements selected in the PERIODIC TABLE window are displayed in the GRAPH and TABLE windows. The PERIODIC TABLE window contains a standard periodic table (elements 1 through 112), as well as buttons that can be used to select or deselect elements. Elements can also be selected or deselected by performing a search in the GRAPH and TABLE windows. See the sections of the documentation on Searching in the GRAPH or TABLE window for more information.
Figure 2.1 – The PERIODIC TABLE window is used to select elements used in the TABLE and GRAPH windows.The elements Zn, Ga, Ge, As, Se, Br and Kr are selected and all other elements are deselected.
Each element in the periodic table is a button. Clicking one of these buttons will select or deselect the element. When the applet starts, all elements are selected (see Fig. 1.1).
Buttons for selected elements appear darker than those of deselected elements. In the Figure 2.1, the elements Zn, Ga, Ge, As, Se, Br and Kr are selected and all other elements are deselected.
An element’s name and atomic number can be displayed in a pop–up label by positioning the mouse cursor over the element button. The pop-up label for germanium (Ge) is displayed in Figure 2.1.
All of the other buttons in the PERIODIC TABLE window are used to select or deselect categories of elements. On the left–hand side of each period (row) in the periodic table is a numbered button that will either select or deselect all of the elements in that period. Similarly, at the top of each group (column), there is a numbered button that will either select or deselect all of the elements in that group. The buttons labeled MAIN GROUP ELEMENTS, TRANSITION METALS, and INNER TRANSITION METALS select or deselect the corresponding elements. If none or only some of the elements in a category are selected, are selected, clicking one of these buttons selects all of the elements in the category. Only if all of the elements in that category are already selected will clicking one of these buttons result in deselecting the elements.
The toolbar at the top of the PERIODIC TABLE window contains five additional buttons. These buttons can be used to select all of the elements in the periodic table (Select All), deselect all of the elements (Deselect All), select all of the metals (Select Metals), select all of the non-metals (Select Non-Metals ), and select all of the semi–metals (Select Semi–Metals).
