Solution

  • The element G has atomic number 9 which defines that the element is fluorine. It has electronic configuration 2, 7 which defines that it can accept an electron to complete its octet.
  • The element G has smaller size and high nuclear charge. Thus, it will have high attraction towards the shared pair of electrons in a molecule. Thus, G has the highest electronegativity.
