Webb1. Chemical reactions result in the gain, loss, or rearrangement of valence electrons. 2. For main group elements, the number of valence electrons equals eight minus the element's group number. 3. Core electrons are not involved in bonding or in chemical reactions. 7. An atom of He has _____ valence electrons. 8. WebbCount the number of lone pairs + the number of atoms that are directly attached to the central atom. This is the steric number (SN) of the central atom. SN = 4 → sp³. SN = 3 → sp². SN = 2 → sp. For example, the O atom in water (H₂O) has 2 lone pairs and 2 directly attached atoms. ∴ SN = 2 + 2 = 4, and hybridization is sp³.
