Question

Atoms having _______ are more likely to form cations.

• A. high electron affinity
• B. high electronegativity
• C. smaller atomic size
• D. low ionisation energy

Answer 1

The correct option is D low ionisation energy

Ionization energy is the amount of energy required to remove an electron from outermost orbit of a neutral atom. Metals have a tendency to loose the electrons and form cations. So, atoms having low ionization energy are more likely to form cations.
