Question

Why do atoms of different elements differ from each other in Mass and properties

Answer 1

Answer:

Normally, the number of electrons is equal to the number of protons, which makes atoms electrically neutral.

The number of protons in an atom is the defining feature of an atom. It's what makes one element different from another. The number of protons in an atom is called its atomic number. Oxygen atoms have 8 protons. So the atomic number of oxygen is 8.

All the elements in the universe are arranged according to their atomic number in the periodic table.
