Question

sum of number of proton electron neutron in 12 g carbon of c12

Answer 1

to find the number of protons, neutrons, and electrons present in 12g of carbon, let's start with the number of Protons, electrons and neutrons in ONE atom of carbon. we have 6 protons, usually 6 neutrons, and 6 electrons per atom of carbon. in 12 g of carbon,we have 1 mole of carbon. so multiply our existing number of protons, neutrons and electrons with the number of carbon atoms present in 1 mole. each mole contains( 6.023*10 raised to 23) atoms in it, we call this Avogadros number(NA). so finally we get 6*NA protons, 6*NA neutrons, 6*NA electrons

Answer 2

in carbon atom there are 6 proton( Z) , 12 electrons ( A) . no of neutrons = A-Z =12-6 =6 neutrons...i hope it will help u ... friend..
