Aluminum   143

Potasium     227

2) Increasing electronegativity

Neon   -

Aluminum        1.61

Sulfur               2.58

Oxygen            3.44

3.-

Electronegativity: is the measure of the tendency of an atom to attract a pair of electrons.

Ionization energy: is the quantity of energy that an isolated, gaseous atom must absorb to discharged an electron, resulting in a cation.

4.-

Atomic radius increases as we move down on the periodic table.

Atomic radius is the distance from the center of a nucleus to the outer most shell containing electrons.

5.-

Sulfur = 1s² 2s² 2p⁶ 3s² 3p⁴

Neon = 1s² 2s² 2p⁶
