Oxygen shares a pair of __________________ with one hydrogen atom and another pair with another ____________________. This sharing of electrons is called a ___________________ bond.

____________________ bonds happen with one atom _______________ an electron from another. The extra electron gives the first atom a ___________________ ______________ and the other atom becomes ___________________ charged because it lost an electron.
