Answer

Answer:

B. iodine

Explanation:

Step1: Determine the total number of electrons

Count the electrons in each sub - shell. $2 + 2+6 + 2+6+2 + 10+6+2+10+5=53$

Step2: Identify the element

The atomic number is equal to the number of electrons in a neutral atom. Iodine has an atomic number of 53.
