Question
The similarity between the subgroup A and B elements is with respect to there –
- Physical properties
- Chemical properties
- Valency
- None
Answer
(b) Chemical Properties
Explanation :
The similarity between the subgroup A and B elements is with respect to their chemical properties. The elements in the same group, also known as the vertical columns of the periodic table, have similar chemical properties because they have the same number of valence electrons, which determines their reactivity and chemical behaviour.
