The atomic number of elements A, B, C and D are Z-1, Z+1, and Z+2, respectively. If ‘B’ is a noble gas, choose the correct answer from the following statements.
V) ‘A’ has higher electron affinity
VI) ‘C’ exists in +2 oxidation state
VII) ‘D’ is an alkaline earth metal
V) ‘A’ has higher electron affinity
VI) ‘C’ exists in +2 oxidation state
VII) ‘D’ is an alkaline earth metal
View answer and explanation
Correct option: C
I and III
Option C (I and III) is correct because if B is a noble gas (Z+1), then A (Z-1) has a high electron affinity and D (Z+2) is an alkaline earth metal.
