Question

For each Li* substituting for Ca²*, one
positive charge is removed; in order to
maintain charge neutrality, a
single negative charge may be
removed.
For Li* substituting for Ca2* in CaO,
oxygen vacancies would be created.
Negative charges are eliminated by
creating oxygen vacancies, and for
every two Li* ions added, a single
oxygen vacancy is formed.
There is no need for vacancy formation
as the charge neutrality is already
maintained if two Li* ions substitutes for
an Ca2* jon.

Li,O is added as an impurity to CaO.
Suppose that Li* ions substitute for
Ca2* ions.
Which statement below is not true for
the formation of vacancies in order to
maintain the charge neutrality? *
