(d) Name the noble gas which has the same electronic configurat
phosphorus ion has. Argon (Ar)]
4. Differentiate between shell and subshell with examples of each.

Answers
Answer:
according to your question the phosphorus ion should be P^3-.
in P^3- ion, 15 protons,18 electrons,16 neutrons are present.
electronic configuration of P^3- ion will be...1s^2 2s^2 2p^6 3s^2 3p^6 just as Argon atom.
the principal quantum no. (n) = 1,2,3,4,....are represented as shells where, according to bohar model of atom....n=1, represent...K shell
n=2, represent...L shell
n=3, represent....M shell
n=4, represent...N shell
(4) while the Azimuthal quantum no.(l) represent subshells of an atom where....
l=0, represent...s subshell
l=1, represent....p subshell
l=2, represent...d subshell
l=3, represent...f subshell
(5) the no. of electron in an atom is equal to its atomic number.....hence answer is 17.
