Detailed explanation-1: -Nonmetals tend to gain electrons to form ions of negative charge. So the correct answer is D. gain, negative.
Detailed explanation-2: -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.
Detailed explanation-3: -Metallic atoms hold some of their electrons relatively loosely. Consequently, they tend to lose electrons and form cations. Conversely, most nonmetallic atoms attract electrons more strongly than metallic atoms, and so gain electrons to form anions.
Detailed explanation-4: -Metals lose electrons in bonding and non-metals gain electrons. So, metals form cations and non-metals form anions.
Detailed explanation-5: -While non-metals have more number of valence electrons, it is easier to gain electrons for them rather than losing to form ions. So non-metals gain electrons and form negative ions.
