An atom has an equal number of electrons and protons.

(C) In a neutral atom,the number of negatively charged electrons is always equal to the number of positively charged protons in the nucleus. This balance ensures that the atom remains electrically neutral. While the number of neutrons can vary (leading to isotopes),the equality between electrons and protons is a fundamental property of any neutral atom.
