What is an example of a chemical symbol?

A chemical symbol is a one-or two-letter designation of an element. Some examples of chemical symbols are “O” for oxygen, “Zn” for zinc, and “Fe” for iron. The first letter of a symbol is always capitalized. If the symbol contains two letters, the second letter is lower case.

WHAT IS A in chemistry?

A is used to signify the atomic mass number (also known as atomic mass or atomic weight) of an atom. A = # protons + # neutrons. A and Z are integer values. When the actual mass of an atom is expressed in amu (atomic mass units) or g/mol then the value is close to A.

Each element is represented by its atomic symbol in the Periodic Table – e.g. H for hydrogen, Ca for calcium. If more than one atom of a particular element is present, then it’s indicated by a number in subscript after the atomic symbol — for example, H2O means there are 2 atoms of hydrogen and one of oxygen.

What is the rule for writing chemical symbols?
