- <em>The symbol for silver on the periodic table is </em><u><em>Ag.</em></u>
Explanation:
The elements are pure substances constituted by one single kind of atom.
Every element has a universal accepted chemical name and a <em>symbol</em> for simplicity of the chemical formulae and to enable scientific communication.
There are 118 known elements and all of them are represented in the <em>periodic table</em>.
The chemical symbol consists of one or two letters. The first letter is always upper case and the second one (if exists) is lower case.
