Question

The first IE of neon (atomic number 10) is significantly higher than that of argon (atomic number 18) but significantly

Answer 1

Explanation:

Different atoms binds their outermost shell electrons with different amount of energy.

The amount of energy required to remove an electron from an atom is the ionization energy.

• Ionization energy measures the readiness of an atom to lose electrons.
• From the given problem, we can infer that in group O the ionization energy decreases down the group.
• Helium has the highest ionization energy.
• Down a group on the periodic table, ionization energy decrease because:

1.  atomic radii increases down the group.
2. there is an increasing shielding/screening effect of inner shell electrons on the outermost shell electrons.
