So what you do is you write out each element separately and how many of that element on either side of the arrow S-8|S-1
O-2|O-2
on one side theres 8 (S) and 2 (O) and 1(S) and 2(O) if you put a number in front to balance it you are multiplying it the elements number like
SO2 if I put a 2 in front now I will have 2(S) and 4(O)
Answer is 1,8,8
Molecule is the general term used to describe any atoms that are connected by chemical bonds.
Every combination of atoms is a molecule. A compound is a molecule made
of atoms from different elements.
Well, if a molecule is considered to be a discrete small unit made up of atoms joined
together, then NaCl, and any other ionic solid is not really a molecule. In NaCl we have a
repetitive crystal structure in which each Na+ ion is surrounded by Cl-
ions, and vice-versa, for as far as the crystal extends. There really isn't such a thing
as an NaCl molecule.
