(i) What is difference between l and 'L'? (ii) Nitrogen has 7 proton

1.	(i) What is difference between l and 'L'? (ii) Nitrogen has 7 protons, 7 electrons and 7 neutrons. Calculate the number electrons, protons and neutrons in N3−ion.
Answer» (i) l represents azimuthal quantum number while L represents second shell of atom. (ii) N^3- No. of protons = 7 No. of electrons = 7+3 = 10 No. of neutrons = 14-7 = 7

(i) What is difference between l and 'L'? (ii) Nitrogen has 7 protons, 7 electrons and 7 neutrons. Calculate the number electrons, protons and neutrons in N3−ion.

Answer»

(i) l represents azimuthal quantum number while L represents second shell of atom.

(ii) N^3-

No. of protons = 7

No. of electrons = 7+3 = 10

No. of neutrons = 14-7 = 7
