Answer 1

A chemical symbol is a shorthand method of representing an element. Instead of writing out the name of an element, we represent an element name with one or two letters.

As you know, the periodic table is a chemist's easy reference guide. As shown below, the periodic table contains the elements arranged by size of the atom that makes up the element and the properties of those atoms. Each element is represented by a chemical symbol consisting of letters. Examples of chemical symbols are shown in the next section.

Answer 2

• The number of atoms in each element and the number of elements in the compound are listed in a chemical formula.
• The symbols for the specific elements in a chemical formula are the letters.
• For example, the letters H, O, S, Cu, F, Fe, and Au stand for hydrogen, oxygen, sulphur, copper, fluorine, iron, and gold.
