If the atomic weight of an element is 12 times that of the lightest element and it has 6 protons, then it contains

Given, Atomic mass= mass no. (A)=12 times that of the lightest element(H)=12Atomic no.(Z)=6=no. of protons = no. of electrons (Since it is a neutral species)no. of neutrons=A-Z=12-6=6
