Two atoms of chlorine are needed, one to accept each of the barium electrons in an ionic compound, barium chloride (BaCl2).
The elements in Barium Chloride (BaCl2) are Barium (Ba) and Chlorine (Cl).
There are 2. The chemical formula tells you that there is 1 barium and 2 chlorine.
Barium's charge is 2+ and Chlorine's charge is 1- so the formula would be BaCl2

Two atoms of chlorine are needed, one to accept each of the barium electrons in an ionic compound, barium chloride (BaCl2).
The elements in Barium Chloride (BaCl2) are Barium (Ba) and Chlorine (Cl).
The name is Barium Chloride because it is the reaction of Barium (Ba2+) with Chlorine (Cl-).
There are 2. The chemical formula tells you that there is 1 barium and 2 chlorine.
Barium's charge is 2+ and Chlorine's charge is 1- so the formula would be BaCl2
Barium gives its two electrons to two chlorine atoms (to form chloride ions) and they form an ionic compound barium chloride.
I think ionic, but I don't know why . . . barium is a metal and chlorine is a nonmetal. barium needs to transfer two electrons to form a +2 cation. each chlorine atom can gain one electron, to form -1 anions. One barium will need two chlorine atoms to form barium chloride, BaCl2, which has ionic bonding.
H2S is the chemical formula for barium chloride.
