Atoms A and B with Lewis structures : un...

Atoms A and B with Lewis structures `: underset(* *)overset(* * )A:` and `:underset(* *)overset(* * )B:` can form a singlet linkage.

Text Solution

AI Generated Solution

To determine whether the statement that atoms A and B can form a singlet linkage is correct or incorrect, we need to analyze the Lewis structures of both atoms and their electronic configurations. ### Step-by-Step Solution: 1. **Identify the Lewis Structures**: - Atom A has the Lewis structure represented as `:underset(* *)overset(* * )A:` which indicates that it has a certain number of valence electrons. - Atom B has the Lewis structure represented as `:underset(* *)overset(* * )B:` which also indicates its valence electrons. ...
