1.	The number of electrons, protons and neutrons in a species are equal to 18, 16 and 16 respectively. Assign the proper symbol to the species.
Answer» Solution :ELECTRONS = 18, PROTONS = 16, Neutrons = 16 ATOMIC number = No. of protons = 16 Mass number = No. of prtons + No. of neutrons `= 16 + 16 = 32` As the species has two electrons more than protons, it has two UNITS of -ve charge. Hence, the species is `._(16)^(32)S^(2-)`
