Question

3/25 what charge will bromine form when becoming an ion? 7+ 7- 1- 0 1+

Explanation:

Bromine is a halogen (Group 17 in the periodic table) with 7 valence electrons. To achieve a stable octet (8 valence electrons), it gains 1 electron. Gaining an electron gives a negative charge, so the bromide ion has a charge of \(1^-\).

Answer:

1- (the option with "1-")
