Explain why Li shows diagonal relationship in property with Mg?

Expert Answer:

Reasons for relationship between diagonally located elements Li and Mg:

  • As we move down the period the electropositive nature increases, but it decreases as we towards right in a period. Hence, the diagonally located elements have similar electropositive character.
  • As we move down the group, the size of the atom increases and hence, the polarising power decreases. But, the size of the atom decreases as we move right in a period and hence the polarising power increases. So, the diagonally located elements show quiet similar properties.
