Question

When one mole of F atoms are ionised to F,
the energy released is X Joules. Then :-
(1) X Joules is sufficient to ionise 1 mole of
gaseous Cl into Ci+
(2) X Joules is sufficient to ionise 1 mole of
gaseous F into F+
(3) X Joules is sufficient to ionise 1 mole of
gaseous F into F+ as well as 1 mole of
gaseous Cl into Cit
(4) Less than 1 mole of gaseous F or Cl atom
will be ionised to F+ or Ci*​

Answer 1

Answer:

Explanation:

(3) X Joules is sufficient to ionise 1 mole of

gaseous F into F+ as well as 1 mole of

gaseous Cl into Cit

Answer 2

The amount of energy required to ionize F and Cl atoms are the same

• F and Cl are two elements that belong to the same group in the periodic table, that is, group 17.
• This implies that they have the same valency as well as similar chemical and physical attributes.
• To ionize one mole of F atoms X energy joules is released since Cl has the same valency, the same amount of energy, that is, X joules will be released upon its ionization.

Thus, the correct answer is (Option 3) X Joules will be sufficient to ionize 1 mole of gaseous F into F+ and similarly 1 mole of gaseous Cl into Cl⁺ .
