Concept explainers
(a)
Interpretation:
The name and formula of the compound formed from cesium and bromine are to be determined.
Concept introduction:
Ionic compounds are those compounds which are composed of ions. An ionic bond is formed when two ions of opposite charges combine due to the electrostatic forces of attraction. Ionic compounds are formed when a metal reacts with a non-metal. Metals have the tendency to lose electrons. Metals lose electrons to form cations whereas non-metals gain electrons to form anions. Cations and anions attract each other and form ionic compounds.
Covalent bonds are formed by the sharing of electrons between two or more atoms. In covalent bonding, there is a mutual attraction between two nuclei and the two electrons that reside between them.
(b)
Interpretation:
The name and formula of the compound formed from barium and sulfur are to be determined.
