Question 26 (1 point) Use the periodic table to determine which statement below is true of the element Bromine (Br).

•Bromine will lose 7 valence electrons to become a negative ion.
•Bromine will lose 7 valence electrons to become a positive ion.
•Bromine will gain 1 valence electron to become a negative ion.
•Bromine will gain 1 valence electron to become a positive ion.

The correct option is;

Bromine will gain 1 valence electron to become a negative ion

Explanation:

Bromine can be found in period 4 in group 17 of the periodic table and is an halogen

The electron configuration of bromine can be presented as follows;

Electronic configuration 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁵

Therefore, an atom of bromine has 2 + 5 or 7 electrons in its outermost shell, which makes it have one less electron to complete a full octet structure and therefore, bromine has a strong affinity for electron to complete its octet structure and it is thus a strong oxidizing agent.

When bromine enters into a chemical reaction and gains the one valence electron it becomes a negatively charged ion.
