Question

What is the proton number, neutron number and electron number of CH4?

Answer 1

)number of electrons present in 1 mole of methane(CH4); {1(6)+4(1)}=10 Number of electrons present in 1 mole i.e.6.023*10 power 23 molecules of methane=6.022*10 power 23*10=6.022*10 power 24 (ii) (a)number of atoms of 14 c in one mole 6.023*10 power 23 Since 1 atom of 14 c contains (14-6) i.e., 8 neutrons,the no. of
