Which element is most likely to gain electrons in a chemical reaction?
tatyana61 [14]
Option 2, Br. I'll go over why all other three options are incorrect.

Option 1 - Krypton is a Noble gas, and so it doesn't need to accept electrons since it has an octet.

Option 3 and 4 - Both Calcium and Barium are alkaline earth metals, and give away electrons, since they only have 2.
