Answer

Brief Explanations:

  1. First, find the total number of electrons from the electron - configuration. The sum of the superscripts gives the total number of electrons.
    • (2 + 2+6 + 2+6 + 2+10 + 6+2 + 10+5=53).
  2. Then, recall that the atomic number of an element is equal to the number of electrons in a neutral atom.
    • The element with atomic number 53 is iodine.

Answer:

iodine
