Detailed explanation-1: -Answer and Explanation: Nonmetals tend to gain electrons to form ions of negative charge. So the correct answer is D. gain, negative.
Detailed explanation-2: -Nonmetals: Nonmetals like to gain electrons to form anions to have a fully stable octet. They release energy (exothermic) to gain electrons to form an anion; thus, electron affinity of nonmetals is higher than that of metals.
Detailed explanation-3: -What does a nonmetal element need to do to form an anion? Nonmetal atoms need to gain one or more electrons.
Detailed explanation-4: -Metals tend to lose electrons and are electropositive in nature whereas non-metals tend to gain electrons and are electronegative.
Detailed explanation-5: -Non-metals always gain electrons to form anions.
