(a)
Interpretation: The compound or ion of a second period element, that has formula and lewis structure analogous to given formula
Concept introduction: The elements belonging to the same group of periodic table have same number of electrons in their valence shell. Thus, their physical and chemical properties are also similar.
These elements can exist in similar oxidation state due to same number of valence electrons in the outermost shell. Hence, the elements of same group form compounds with same formula.
If two elements belongs to
However, the lighter elements of the group do not expand their octet while the heavier elements can expand their octet and form compounds with different oxidation numbers. So if the elements belong to group
So, the same number of valence electrons in outermost shell of the elements in same group is responsible for the similar chemical properties of these elements. Thus they also form compounds with same formula.
