Detailed explanation-1: -2: A chlorine atom (Cl) has equal numbers of protons and electrons (17) and is uncharged. When it gains an electron, the resulting chlorine anion has one more electron (18) than protons (17), giving it an overall negative one charge, Cl–.
Detailed explanation-2: -A neutral chlorine (Cl) atom that gains one electron changes into a chloride ion (Cl-) with a charge of 1– (see Table 2.8).
Detailed explanation-3: -Since chlorine gained an electron it has 17 protons and 18 electrons. This makes chloride a negative ion with a charge of −1. The positive sodium ion and negative chloride ion attract one another.
Detailed explanation-4: -Metals tend to lose electrons and form positively charged ions called cations. Non-metals tend to gain electrons and form negatively charged ions called anions.
