Detailed explanation-1: -When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral.
Detailed explanation-2: -All atoms have the same number of electrons as protons, so the positive and negative charges “cancel out", making atoms electrically neutral.
Detailed explanation-3: -If there are equal numbers of protons and electrons, then the object is electrically neutral.
Detailed explanation-4: -Statement I: A neutral atom carries no net charge. Statement II: An atom that has equal number of protons and electrons is called a neutral atom.
Detailed explanation-5: -Answer: An electron is a negatively charged particle and a proton is a positively charged particle. As negative charged attracts the positive charged and vice versa, both electron and proton stays together so that overall charge is zero / neutral. Thus an atom always has equal electrons and protons to remain neutral.
