Question

Br, Br- which is large in size

Answer 1

Answer:

Br-

Explanation:

Since the outermost shell of Br- is complete, all electrons repel each other and increase the atomic size of the ion.

Answer 2

Br - will have the largest atomic size because Br- has one extra electron in its valence shell which due to its unbalanced negative charge will be repelled and hence the atomic radius of Br- will increase.
