NH4 contains two different elements. They are nitrogen (N) and hydrogen (H).
One molecule of NH4 has 5 atoms. Two molecules of NH4 will have 10 atoms, and so on. So, the number of atoms depends on the number of molecules.

...as a solid.
NH4+ has 4 bonds. Each of the hydrogen atoms is bonded to the nitrogen atom in NH4+.
When (NH4)3PO4 dissolves in solution, it will dissociate into 3 ammonium ions (NH4+) for every molecule of (NH4)3PO4 that dissolves because each (NH4)3PO4 molecule contains three NH4+ ions.
There are 8 atoms of hydrogen present in NH4 2S. This is because there are 4 hydrogen atoms in each ammonium ion (NH4+) and there are 2 ammonium ions in NH4 2S.
NH4 WILL HAVE 1 LONE ELECTRON AS 4 GOT INCLUDING IN BONDING BUT IT CAN BE INSTEAD NH4+ THUS THE LONE ELECTRON HAS BEEN LOST THUS NH4+ HAS 4 bond pairs and no lone pairs
The columns organise the elemnts according to the number of valence electrons that give rise to many of the similarities between the chemistry of the elemnts in the column. The rows organise in increasing atomic number.
"NH4" I assume is NH4+This is the ammonium ion.
the ion NH4+ has five atoms (one nitrogen and four hydrogen)
0.63 mol of (NH4)2SO4 contain 3,978.10e23 hydrogen atoms.
NH4 is colorless.
