Answer 1

the number of electron of a neutral atom is always equals the number of proton

Answer 2

The correct statement is the number of electrons of a neutral atom always equals the number of protons.

Atom:

• Chemistry's fundamental building block is an atom.
• It is the smallest fraction of matter into which electrically charged particles cannot be released.
• It is also the smallest piece of substance with chemical element-like characteristics.
• The ratio of neutrons to protons is not always the same.
• The ratio of neutrons to electrons is not always the same.
• The charge number of an atomic nucleus is the chemical element's atomic number, also known as the nuclear charge number.
• This is equivalent to the proton number, or the number of protons present in the nucleus of each atom of that element, for conventional nuclei.
