What is the definition of valence electrons?

Back

Electrons in the outermost shell of an atom that are involved in bonding.

Front

What is the significance of lone pairs in molecular geometry?

Back

Lone pairs can affect the shape of a molecule by repelling bonding pairs.

Front

What is the octet rule?

Back

Atoms tend to bond in such a way that they have eight electrons in their valence shell.
