Question

What affects the shape of molecule

Answer 1

The shape of a molecule is affected by the arrangement of electrons, but does not describe that arrangement. The “shape” of a molecule is how the outside atoms are arranged around the central atom. The lone pairs of electrons affect this arrangement, but are not part of it.

Answer 2

The shape of a molecule is determined by the location of the nuclei and its electrons. The electrons and the nuclei settle into positions that minimize repulsion and maximize attraction.
