Concept explainers
(a)
Interpretation:
The element of group 5 A that forms strong p bonds needs to be determined.
Concept introduction:
The group 5A elements show variation from non-metals to metals down in the group. The first element of the group 5A is nitrogen with 5 valence electrons.
The group 5A is a combination of non-metal, metalloid and metals. The first element of the group 5A is nitrogen with 5 valence electrons. Here nitrogen and phosphors are non-metals, arsenic and antimony are non-metals and bismuth are the only metallic element of group 5A.
(b)
Interpretation:
The element of group 5 A that is metal needs to be determined.
Concept introduction:
