Interpretation:
The chemical formulas of barium sulfate, magnesium nitrate and sodium acetate has to be determined. Also, the names and electrical charges of monoatomic cation and polyatomic anion has to be given.
Concept Introduction:
An atom or a molecule having a net electrical charge is known as atom. Charge of the electron is negative and charge of the proton is positive. Both electron and proton have the same magnitude. Positively charged ion is called cation and negatively charged ion is called anion. Because of the opposite charge of cation and anion they will readily form ionic compounds. Ions consisting of only a single atom known as monoatomic ions and more than two atoms form polyatomic ions.
