How many elements are there?

The periodic table, also called the periodic table of elements, is an organized arrangement of the 118 known chemical elements.

What is the valence of each element?

Valency is the combining power of an element, and it determines how many atoms of an element a particular atom can combine with. As a result, in H2O, oxygen (O) has a valence of 2 ( recall that hydrogen is assigned a valence of 1). In H3N, the valence of nitrogen (N) is 3, and in H4C the valence of carbon is 4.
