Question

Fill in the blanks by selecting the correct word from the brackets.
(i) If an element has low ionization energy, then it is likely to be ______ (metallic/non-metallic).

Answer 1

Metallic character:-

• It is the ability or tendency of an element to lose electrons in order to form cations.
• Metallic character increases down the group and decreases across a period from left to right. Similarly, ionization energy decreases while moving down the group and increases across a period.
• Therefore, if the ionization energy of an element is low, it means that less energy is required to remove an electron from the outermost shell to form a cation. As a result, the metallic character of the element increases.

Thus, If an element has low ionization energy, then it is likely to be metallic.
