Question

state 2n² rule pf bohr and bury. Draw diagram indicating the distribution of electrons in an atom of the element having atomic numbers 8 and 17. Give the names and symbols of these elements​

Answer 1

Answer:

in general, the maximum number of electrons that can be present in any shell is 2n² where n is the number of energy shell

Thus, the first orbit (n=1 known as k shell) can contain 2 2 X 12= 2 electrons, the second orbit(n=2 known as L shell) can contain 2 X 22=8 electrons
