There are 2. The chemical formula tells you that there is 1 barium and 2 chlorine.
3
Two atoms of chlorine are needed, one to accept each of the barium electrons in an ionic compound, barium chloride (BaCl2).
Barium sulfide (BaS) has two atoms.
Barium hydroxide - Ba(OH)2: 5 atoms.
Fluorine is an element and barium is also an element. There is no fluorine in barium and not barium in fluorine.

Barium gives its two electrons to two chlorine atoms (to form chloride ions) and they form an ionic compound barium chloride.
Ionic salts as barium chloride form lattices.
Two
Barium chloride is BaCl2
Two atoms of chlorine are needed, one to accept each of the barium electrons in an ionic compound, barium chloride (BaCl2).
Since both barium chloride and barium sulfate contain one mole of barium atoms pert mole of compound, the moles of barium sulfate will be the same, 0.100, when barium has the limiting concentration in the production of the sulfate.
Barium Dichloride is NOT correct. The name is Barium Chloride it is a binary ionic compound.
6.022 x 1023 molecules. This is Avogadro's number and a mole of anything. Since there are three atoms in each molecule, one of Barium and two of Chlorine, the number of atoms is three times that, or 1.807 x 1024.
Barium chloride can be precipitated wit a sulfate; barium sulfate is then filtrated.
Barium sulfide (BaS) has two atoms.
Barium hydroxide - Ba(OH)2: 5 atoms.
Barium chloride is the name of the compound with the formula BaCl2.
