Full Answer

Covalent bonding must occur for the atoms of hydrogen and oxygen to join together to form water. In a covalent bond, atoms share electrons. This is the opposite of ionic bonding, in which electrons are transferred between atoms. Water freezes at 32 degrees Fahrenheit and boils at 212 degrees Fahrenheit. Water is less dense in its solid form than its liquid form.
