For methane, which has four bonding pairs and no unshared pairs, the bonding pairs are furthest away when the angle between the central carbon and it’s attached hydrogens is 109.5, giving a tetrahedral shape.

to have the electrons farthest apart, methane has a bonding angle of 109.5 between each bond. A tetrahedral shape

why does methane form a tetrahedral shape?
