Atoms are neutral; they contain the same number of protons as electrons. A neutral sodium atom, for example, contains 11 protons and 11 electrons. By removing an electron from this atom we get a positively charged Na+ ion that has a net charge of +1. Atoms that gain extra electrons become negatively charged.Click to see full answer. Also question is, what is a neutral atom?An atom that has equal number of protons and electrons is called a neutral atom. A neutral Sodium atom has atomic # 11, which means , it has 11 protons and since it is neutral, it also has 11 electrons.Likewise, how many protons neutrons and electrons are in a neutral atom of sodium? The element sodium has 12 neutrons, 11 electrons and 11 protons. The number of electrons and protons come from the element’s atomic number, which is same 11. The number of neutrons can be found by subtraction of the atomic number from sodium’s atomic mass of twenty three. Thereof, why is sodium electrically neutral? Now since the charged are always added integrally, the net charged on an atom comes out to be 0 and the atom is therefore electrically neutral. Now, a sodium atom becomes an in when it donates one of its electrons to complete its octet. The charge of this one extra protons is what gives the sodium ion its +1 charge…How many valence electrons are in a neutral atom of sodium? 11 electrons
