Barium nitride is Ba3N2 (from the rules of ionic bonding). Its molar mass is 439 grams/mole (from the Periodic Table), so 18.8 grams of it is 0.0428 moles (by algebraic direct proportion). Multiply this by Avogadro's number (6.02x1023; the number of particles in 1 mole) and you get 2.58x1022 formula units of barium nitride, and there are 2 nitrogen atoms per formula unit, so double it to 5.16x1022 atoms of nitrogen.
Yes. Aluminum nitride does exist. I am providing a link to a company's website detailing the properties and uses of aluminum nitride. http://www.ceramtec.com/ceramic-materials/aluminum-nitride
Totally three atoms One barium and two chlorine atoms
The formula for magnesium nitride is Mg3N2, so there are two nitrogen atoms present in a single molecule of magnesium nitride. In this case, the magnesium has a +2 charge, and the nitrogen has a -3 charge, which accounts for why more than one of each must come together and form a molecule (the total charge needs to be zero).
There are 2 nitrogen atoms in 2NH3.
In the formation of potassium nitride, the nitrogen atom transfers 3 valence electrons to the potassium atom. This results in the nitrogen atom achieving a full outer shell, becoming a nitride ion with a charge of -3, and the potassium atom becoming a potassium ion with a charge of +1.
The formula unit for calcium nitride is Ca3N2. That would be 3 atoms of calcium and 2 atoms of nitrogen, for a total of 5 atoms in a formula unit.
Barium nitrate, Ba(NO3)2: Ba - 1 atom Nitrogen - 2 atoms Oxygen - 6 atoms Total - 9 atoms

Barium sulfide (BaS) has two atoms.
The number of atoms is 101,341.10e23.
Fluorine is an element and barium is also an element. There is no fluorine in barium and not barium in fluorine.
Totally three atoms One barium and two chlorine atoms
Seven from the nitrogen atom, eight from each of the three oxygen atoms, and one more from a metal or group that forms a nitrate salt, for a total of 32.
The formula for magnesium nitride is Mg3N2, so there are two nitrogen atoms present in a single molecule of magnesium nitride. In this case, the magnesium has a +2 charge, and the nitrogen has a -3 charge, which accounts for why more than one of each must come together and form a molecule (the total charge needs to be zero).
Sodium nitride (Na3N) has 3 sodium atoms in the formula unit.
There are 2. The chemical formula tells you that there is 1 barium and 2 chlorine.
There are 2 nitrogen atoms in 2NH3.
