Concept explainers
(a)
Interpretation:
The chemical formula for the compound Nickel (II) nitrate has to be written.
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.
(b)
Interpretation:
The chemical formula for the compound sodium bicarbonate has to be written.
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
The chemical formula for the compound lithium hypochlorite has to be written.
Concept Introduction:
Refer to part (a).
(d)
Interpretation:
The chemical formula for the compound magnesium chlorate has to be written.
Concept Introduction:
Refer to part (a).
(e)
Interpretation:
The chemical formula for the compound calcium sulfite has to be written.
Concept Introduction:
Refer to part (a).
