(a)
Interpretation:
The name of the ionic compound formed from potassium and sulfur is 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.
(b)
Interpretation:
The name of the ionic compound formed from iodine and barium is 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.
