(i) What is the atomic number of the atom? and
(ii) What is the charge on the atom?
Answer :
Given: Number of electrons = 8
Number of protons = 8
(a) The atomic number of an atom is the same as the number of protons in that atom, hence its atomic number is 8.
(b) In an atom, if the number of protons is equal to the number of electrons then both the charges i.e., the positive charge and negative charge neutralize each other. In this case the atom has an equal number of electrons and protons, therefore the atom does not possess any charge.
