Vedclass · Answer

(C) The statement that the number of protons is equal to the number of neutrons is false.In a neutral atom,the number of electrons is equal to the number of protons.Key points regarding atomic structure:$1$. The number of protons in the nucleus is equal to the atomic number $(Z)$.$2$. In a neutral atom,the number of electrons equals the number of protons.$3$. The mass number $(A)$ is the sum of the number of protons and neutrons.$4$. The number of neutrons is calculated as $(A - Z)$.Therefore,the number of protons and neutrons is not necessarily equal.
