Question

What about electronegativity. Atomic radius ionisation enthalpy .In.The periodic table?

Answer 1

Answer:

From top to bottom down a group,electronegativity decreases. This is because atomic number increases down a group, and thus there is an increased distance between the valence electrons and nucleus, or a greater atomic radius.

Answer 2

Answer:

electronegativity increases from left to right same as ionisation enthalpy while atomic radius decreases from left to right

in case of top to bottom these properties become just opposite
