Concept explainers
(a)
Interpretation:
A soft, waxy solid that consists of carbon and hydrogen only has to be classified as ionic or non-ionic based on the name or description.
Concept Introduction:
Ionic compounds:
An atom or a molecule having a net electrical charge is known as ion. 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 substance ammonium oxalate has to be classified as ionic or non-ionic.
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
A hard, brittle solid that melts above
Concept Introduction:
Refer to part (a).
(d)
Interpretation:
An alkali metal oxide has to be classified as ionic or non-ionic.
Concept Introduction:
Refer to part (a).
