Question

chemistry behind atomic radius and ionization energy-why

Answer 1

atomic radius as we move from top to bottom in a periodic table the atomic radius increases

this is because each time an extra shell is being added.

as me move from left to right in a periodic table the atomic radius decreases

atomic radius as we move from top to bottom in a periodic table the ionisation energy decreases since the atomic radius increases.Therefore it is difficult to easy to remove an electron from the atom since the nuclear attraction on the outermost electron decreases

as me move from left to right in a periodic table the ionisation energy increases
