The atom's atomic number is equal to the number of protons in its nucleus.

For example, an element with 19 protons in its nucleus is Potassium (K), the 19th element on the Periodic Table.

What identify the number of protons neutrons and electrons in the atom.?

The number of protons in an atom is equal to its atomic number, which identifies the element. Neutrons are found by subtracting the atomic number from the mass number. For a neutral atom, the number of electrons is equal to the number of protons.
