Added in the case in which we're given 2 Hydrogens since they have the POTENTIAL to bond if we give them an alkali earth metal.  Also, 2 halogens (of the same type I believe [waiting to hear back about it]) will form a bond with an alkali earth metal.  But, for example, 2 Flourines will make Flourine gas.  We need to decide if that is a bond or not.  I have the code in there but it is commented out.  Requires discussion.
