Question

What is the total electron number for Bromine negative ion: Br- ?

a. 53

b. 54

c. 7

d. 36

e. none of the above

Answer 1

Answer #1

option d is the correct answer

atomic number of Br is 36

when Br gains one electron it forms Br-

gains one electron means atomic numer will increase so 35+1 = 36 is the correct answer

Answer 2
