The geometry around a given atom is determined solely by the bonding electrons and the around it.

Lone pairs around it which are the electrons around an atom that are not taking part in a covalent bond but still take up space and affect the shape of the molecule.

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
