Detailed explanation-1: -Thus, the given statement is true i.e.the number of protons and electrons is always the same in a neutral atom.
Detailed explanation-2: -So in a neutral atom, it is not necessary that protons and neutrons are equal in number. So this statement is false. We can say that this one is going to be true. This statement is false.
Detailed explanation-3: -The number of protons in a nucleus is called the atomic number and always equals the number of electrons in orbit about that nucleus (in a nonionized atom). Thus, all atoms that have the same number of protons–the atomic number–are atoms of the same element.
Detailed explanation-4: -The atomic number equals the charge on the nucleus. It therefore also equals the number of protons in the nucleus and also equals numerically the number of electrons in the neutral atom. The atomic number has the symbol Z.
