Question

The first ionization potential of na, mg and si are respectively 496, 737, 786kj per mol . The ionization potential of al will be closer to?

Answer 1

Answer:

760

Explanation:

by taking mere mean and it will be >737 &<786.

Answer 2

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\purple{R}}}}$

• It will be more close to ${575kJmol^-1}$ The value for ${Al}$ should be lower that that of ${MG}$ because of effective sheilding of ${3p}$ electrons from the nucleus by ${3s}$ _electrons.
