The 'Goal' of atoms is to have a total of 8 electrons. So if 1 atom has 5 electrons, and the other has 3, then it is possible for them to combine into a compound. The fusion of two atoms can happen by itself, but that is the extent of my knowledge on the subject.
A compound
No. 4 oxygen atoms have 8 valencies between them whereas 2 hydrogens have only 2.
They gain or lose electrons, while the atoms combine.
Atoms that chemically combine form a molecule.
The combination of the atoms releases heat energy.
