Question

if the K and L shells of an atom are full and the M shell has 2 electrons then what is the atomic number of the atom.​

Answer 1

Answer:

$\huge\boxed{\tt\purple{❥︎AnSweR༄}}$The maximum number of electrons that can be occupied in the K and L-shells of an atom are 2 and 8 respectively. Therefore, if the K and L-shells of an atom are full, then the total number of electrons in the atom would be (2 + 8) = 10 electrons.
