Question

The correct symbol of the species with number of electrons, protons and neutrons as 18,16 and 16 respectively is (A)  3216S  (B)  3218S  (C)  3216S2-  (D)  3218S2-

Tardigrade Admin · Accepted Answer

Number of protons = Atomic number = 16 Thus, the element is sulphur Further, mass number = number of protons + number of neutrons =16 + 16 = 32 Since, number of electrons are greater than the number of protons, so it must be an anion (i.e., obtained by accepting two electrons Hence, the correct symbol of the species must be 3216S2-
