Expert Solution

The energy requred to remove an electron from the outermost shell of a neutral gaseous atom is known as ionisation energy (E_a). Ionisation energy depends on the follwing factors

(a) Atomic size: E_a decreases with increase in atomic size

(b) Nuclear charge: E_a increases with increase in nuclear charge.

(c) Electronic configuration: Atom with fully filled or exactly half-filled orbitals have higher E_a.

Generally E_a decreases from top to bottom in a group and increases from left to right along a period.

Electronic configuration of the given elements are:

Mn = [Ar] 3d⁵4s²

F = 1s²2s²2p⁵

Ne = 1s²2s²2p⁶

Cs = [Xe]6s¹

Among the elements, E_a of Ne is the highest because of its stable configuration of 2s²2p⁶. E_a of Cs will be the lowest. The order of E_a will be Ne > F > Mn > Cs.
