Question

An ionic bond can be formed between two atoms when

(a) one of them has a low ionization energy and the other a high

electron affinity

(b) both the atoms have low values of ionization energy

(c) both the atoms have high values of ionization energy

(d) both the atoms have low values of electron affinity
what's the correct opt? ​

Answer 1

Answer:

The correct option is (a). As the one having low IE will lose electron to form cation and the other having high EA will gain the electron readily forming an anion.

Answer 2

An ionic bond can be formed between two atoms when A) one of them has a low ionization energy and the other a high electron affinity.

How is IONIC BOND formed?

• Ionic bond is formed by gain/loss of electrons.
• An electropositive element ionises to form a cation by loss of electron.
• An electronegative element gains an electrons to form an anion.
• To loss an electron, an element must have Low ionisation energy.
• To gain an electron, an element must have High Electron affinity.
• Example : A + B → AB

1. A → A⁺ - e⁻
2. B → B + e⁻

• A have low ionisation energy and B have High Electron affinity thus, they form an ionic bond.
