Question
- What is difference between 'l' and 'L'?
- Nitrogen has 7 protons, 7 electrons, 7 neutrons. Calculate the number of electrons, Protons and neutrons in N3-ion.
✓
Answer
- ‘l’ represents azimuthul quantum number which determines shape of orbital e.g. l = 0 is s-orbital (spherical)
'L' represents 2nd shell or orbit or energy level.
- N3- is formed when ‘N’ atoms gains 3 electrons
Number of electrons in N3- = 7 + 3 = 10 electrons
Proton in N3- = 7
Neutrons in N3- = 7
