List the element symbols The following are the 8 groups of the periodic table: The main group elements of the periodic table are groups 1, 2 and 13 through 18. Because adding an electron shell pulls the valence electrons further away from the nucleus, electronegativity falls as you move down a group. However, its presence in ocean water has given it a role in biology (see below). The group number is equal to the number of valence electrons if the element is in the s block. In a similar way to aluminium salts, indium(III) ions can be toxic to the kidney when given by injection, but oral indium compounds do not have the chronic toxicity of salts of heavy metals, probably due to poor absorption in basic conditions. The value of n for the outermost or valence shell is shown by the period. Indium's current primary application is to form transparent electrodes from indium tin oxide in liquid crystal displays and touchscreens, and this use largely determines its global mining production. There are four ways to find the charge of an element: Use the periodic table. The average concentration of cadmium in the Earth's crust is between 0.1 and 0.5 parts per million (ppm).
