forming anions\nwhich of the following is most likely to form an anion?\ntransition metals\ngroup 1a alkali metals\ngroup 7a halogens\ngroup 8a nobel gases
Answer
Brief Explanations:
Anions are negatively - charged ions formed when an atom gains electrons. Halogens in Group 7a have 7 valence electrons and need to gain 1 electron to achieve a stable octet configuration, making them highly likely to form anions. Transition metals usually form cations by losing electrons. Group 1a alkali metals also form cations by losing their single valence electron. Noble gases in Group 8a have a stable electron configuration and are very unreactive, rarely forming ions.
Answer:
Group 7a halogens
