I am not sure of the exact numbers of dots, and crosses, however if ammonia can form only three bonds, then the folliwing is correct:
sorry had drawn image in paint but can'y put it in lol stupid moderators. So draw one circle
then overlap three other circles with it, none touching each other
then label the centre 'N'
and the others 'H'
and put a dot and a cross in each overlapping section
(there should be three dots and three crosses in the whole diagram
------------------------------------------------------------------------
[EDIT] Actually the formula for an ammonia ion is NH4+ Due to dative bonding the 4th hydrogen loses an electron making it a positive ion and allowing it to form a dative bond with the Nitrogen. Meaning the nitrogen donates 2 electrons to this 4th hydrogen, completing it's shell.
The diagram would be an N in a circle then 4 circles around it overlapping. A dot and a cross in 3 of them and then 3 dots in the final circle.
Ammonium Chloride is an ionic NH4Cl

Have Nitrogen in the middle with the three Hydrogens each forming a single bond with it.

Refer to the related link for an illustration of the formation of sodium chloride using Lewis dot structures.

Louis Dot created the Dot Diagram.
dot diagrams are called line graphs because there is no such things as a dot diagram.so search in Google images a line graph
Louis Dot, like no joke
A Dot-And-Cross Diagram only shows the outer layer of the covalent bond's electrons.
Dot diagrams, are diagrams that show the bonding between atoms of a molecule, and the lone pairs of electrons that may exist in the molecule.
They can also be called Lewis Dot Structures or Diagrams, named after a scientist names Gilbert Norton Lewis
For bonding between atoms we usually show the dot-cross diagram representing the outer most electrons of bonded atoms.
Lewis structures are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule. They are also called Lewis dot diagrams, electron dot diagrams, and electron dot structures. See the link below for Lewis structure.
I found out that electron dot diagrams can be helpful because, what if you want to have an easier way to represent the atoms and the electrons in the outer energy level then electron dot diagrams are much easier to use.
