Question

what is the molecule polarity for the beh2 molecule? nonpolar polar metallic ionic

Explanation:

To determine the polarity of \(BeH_2\), we first look at its molecular geometry. Beryllium (\(Be\)) has 2 valence electrons and forms two single bonds with hydrogen (\(H\)) atoms. Using VSEPR (Valence - Shell Electron - Pair Repulsion) theory, the electron - pair geometry and molecular geometry of \(BeH_2\) is linear (\(H - Be - H\)).

In a linear \(BeH_2\) molecule, although the \(Be - H\) bonds are polar (because of the difference in electronegativity between \(Be\) and \(H\), with \(H\) being more electronegative than \(Be\)), the bond dipoles are equal in magnitude and opposite in direction. They cancel each other out.

Metallic and ionic are not related to molecular polarity. Metallic refers to a type of bonding in metals, and ionic refers to a type of compound formed by the transfer of electrons (not a property of molecular polarity).

Answer:

nonpolar
