zale101 · Answer

Sodium Chloride
Sodium is Na and has a +1 charge
Chloride is Cl and had a -1 charge
+1-1=0, that means there charges balances out
Chemical formula for sodium chloride is therefore $\large NaCl$

zale101 · Answer

ionic species of that compound is $\large Na^+~Cl^-$
can you do that for hydrogen bromine ?

zale101 · Answer

Hydrogen Bromine is an ionic compound, because it consists of a cation and anion. That makes it also consisting of ionic species.
