Hybrid orbitals are formed by combining the valence orbitals on an atom. A molecule has sp3 hybridization with 2 lone pairs. a. The electron pair geometry of this molecule is:
b. The geometry of this molecule is:

Tetrahedral

Bent

Explanation:

A molecule in sp3 hybridization is ordinarily expected to exhibit tetrahedral electron domain geometry. This implies that it has four electron domains.

We were specifically informed in the question that two lone pairs are present. Remember that lone pairs distort the molecular geometry away from the expected geometry based on VSEPR  theory.

Therefore, the bond angle of the molecule is <<109.5 degrees and its molecular geometry is bent (e.g water)

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
