Question

What is the total number of electron domains in the molecule with the molecular formula AX6?

1) 4
2) 5
3) 6
4) 7

Answer 1

In an AX6 molecule, there are six electron domains, all of which are bonding pairs associated with the six atoms attached to the central atom.

Step-by-step explanation:

The total number of electron domains in a molecule with the molecular formula AX6 is based on the number of bonding sites around the central atom, A. Each X represents an atom bonded to A, and in this case, there are 6 such bonds. No lone pairs are mentioned, so we only count bonding domains. Therefore, the answer is, there are six electron domains in the molecule AX6.
