Concept explainers
(a)
Interpretation:
The equations to represent the positive and negative ion formation for the given pair of elements are to be stated. The formula for the ionic compound that results if the formed ions combine together is to be stated.
Concept introduction:
The species that are formed by losing or gaining the electrons are known as ions. The cations are formed by losing one or more than one electron from the outer most shell of an atom. Anions are formed by gaining one or more than one electron to the outer most shell of an atom.
(b)
Interpretation:
The equations to represent the positive and negative ion formation for the given pair of elements are to be stated. The formula for the ionic compound that results if the formed ions combine together is to be stated.
