Question

electron affinity of k +is numerically equal to​

Answer 1

Answer:

please follow me and I follow you

Explanation:

The electron affinity of an atom is numerically equal to the ionization potential of uninegative ion.

X

−

−e

−

→X ⟹ Ionization potential of atom's uninegative ion

X+e

−

→X

−

⟹ Electron affinity of the atom

Answer 2

Answer:

Electron affinity of K+ is numerically equal to Ionization potential of negative ionisation energy of K+.

Explanation:

The energy released when one mole of neutral gaseous atoms gains one mole of electrons to create the -1 anion is known as electron affinity. 

The energy required to remove the "extra" electron and return to the neutral atom is the ionisation energy of the -1 charged anion. These two energies are exactly the same.

For example,  electron affinity  of K+ Equals to the ionisation energy of K+.

But don't get the ionisation energy of a neutral atom mixed up with its electron affinity. Those are two distinct figures. The EA generates a -1 ion. The consequence of the ionisation is a +1 ion.

Electron affinity  is numerically equal to Ionization potential of negative ionisation energy.
