A list of all chemical elements known to mankind sorted by the number of protons they contain within the atom. As of 2021, there are 118 elements starting with hydrogen, which has one proton.

The same chemical symbols are used all over the ... you can make predictions about the other elements in a group. For example, all the elements in group 1 are reactive metals, and all the elements ...

The modern periodic table sorts all chemical elements in a logical way based on their atomic numbers. The periodic table correlates the atomic structure of each element with its position in the table.

A chemical element is one of those squares on the periodic ... it helps to first understand that atoms, the basic units of all matter, are made of protons, neutrons and electrons.

A GLANCE at the history of the chemical elements reveals the fact that no fewer than fifty-three of them were recognised so early as 1818, and since that time some thirty more have been discovered.
