why n=3 shell cannot hold more than 8 electrons
sir, in your video lecture you have said that n=3 shell can hold 18 electrons, but it cannot hold more than 8 electrons, my question is if n=3 cannot hold more than 8 electrons then the first rule and second rule of atomic distribution is wrong or we can write n=3 can hold only 8 electrons. Explain.
One shell of an atom can hold the number of electrons according to 2n2 format. where n=number shell.
Here for m shell, n=3, So k shell can hold maximum 2(3)power2= 18 electrons means n=3 shell can hold maximum 18 number of electrons. But for the stable electronic configuration outer most shell must have 8 number of valance electrons. If n=3 is out most shell of the atom . it can hold 8 number of electron for the stability.
