C. a scientific approach to answering questions
Answer:
Q = ne
Explanation:
Ler n be the number of electrons transferred and Q be the charge of an ion.
The net charge on the object is then given by :
Q = ne
Where
e is the electronic charge
Hence, the charge of an ion relates to the number of electrons transferred is equal to Q = ne.
Answer: True
