As opposed to bonding in which a complete transfer of electrons occur, bonding occurs when two or more elements electrons. Covalent bonding occurs because the atoms in the compound have a similar tendency for electrons (generally to electrons). This most commonly occurs when two bond together. Because both of the nonmetals will want to electrons, the elements involved will share electrons in an effort to their valence shells.

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
