Thenumberof electronsprotons and neutronsin aspeciesare equalto 18,16

1.	Thenumberof electronsprotons and neutronsin aspeciesare equalto 18,16 and16 respectively . Assigh the proper symbolto the species.
Answer» Solution :Numberof electron=18 Atomicnumber= numberof protons( z) = 16 Numberofneutron (n ) in sulphur = 16 A= massnumber= z+ n Numberof electron(18) `lt`numberproton(16) (18-16)=12electronisexcess chargeis -2so SYMBOL of NEGATIVE ION : `s^(2)` Symbolof species`._(16) ^(18) S^(2)`
