Which side of the following chemical equation is the product side: 2H2 + O2 yields 2H2O?
Right side
No, it is NOT balanced
It tells you the number of molecules of that compound that are formed.
Argon
it gains an electron in its valence level
Since opposite charges are attracted to each other, the ions arrange themselves next to an oppositely charged ion.
it loses an electron from its valence level
