Which among these diatomic molecules is joined by a triple covalent bond? WebLet's consider NaCl in more detail. A sodium atom has 11 protons and 11 electrons. It has a neutral charge. The Na + ion is formed from the loss of one electron. Because it has lost an electron, it has more protons than electrons; the overall charge of the sodium cation is positive. We've always found it useful to think of the "t" in cation as ...
