One evening last summer, as I strolled along the promenade in Limbe, a small, scenic port town in southwestern Cameroon, I was stopped by a well-dressed young man who greeted me warmly and took me by the hand.
Phosphorus has 3 shells. The outer shell contains 5 electrons. The electronic configuration is :- <br /> 1s2, 2s2, 2p6, 3s2, 3p3.
If the shell number if 2, the maximum number of electron present in the first âLâ shell is 2 (2) 2 = 8. If the atoms have 8 electrons in their outer most electron shell, atoms are more stable, and except first electron shell is more stable with two electrons.o the atom of sodium contains 11 numbers of protons and 11 number of electron in electron shell and 23 -11 = 12 numbers of neutrons. First shell contains 2 electrons since it can hold only 2 electrons, then the second shell can hold only 8 electrons, so it contains 8 electrons in second shell.
