Answer 2

Answer:

Ionization potential order is " $Cl\leq S\leq Si \leq Na\leq K$

Explanation

The real ionisation potentials (KJ mole-1) of the elements are listed below, in order of increasing ionisation potential:

$1256 \leq 999\leq 786\leq 496 \leq 419$

The amount of energy necessary to remove an electron from an isolated atom or molecule is called ionisation energy, or ionisation potential.

It is more difficult to remove an electron when the ionisation energy is large.

The following factors influence ionisation energy:

• The size of an atom (A)
• Amount of nuclear energy
• The impact of screening or shielding - Screening constant Zeff = Total nuclear charge (Z)–Zeff = Total nuclear charge (Z)–Zeff = Total nuclear charge (Z)–Z (s)

• The electron penetration effect, defined as s = p > d > f.
