1.	Find out the number of neutrons, protons, and electrons of 17Cl^37 respectively.(a) 20, 20, 17(b) 17, 17, 20(c) 20, 17, 17(d) 17, 17, 17This question was posed to me in final exam.This interesting question is from Atomic Models topic in chapter Structure of Atom of Chemistry – Class 11
Answer» Right answer is (C) 20, 17, 17 To explain I would SAY: An atom is written in the symbol ZXA. By COMPARING it to 17Cl^37, we get a number of protons as 17 and mass number as 37. Mass number – proton number = neutron number. Number of neutrons is 37 – 17 = 20. No. of protons = No. of electrons = 17.
