Question

What is 1s 2s 2p 3s 3p?

Answer 1

1. 1s 2s 2p 3s 3p are the electronic orbitals' energy levels.
2. One atom can have many electronic orbitals due to which energy levels are categorized as specific quantum numbers: 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f 6d 7p.
3. We can get the idea of the orbital angular momentum quantum number denoted by l.
4. For s, p, d, and f orbitals, the orbital angular momentum quantum number (l) is 0,1,2 and 3 respectively.
5. In these orbitals the probability of finding an electron becomes maximum.
6. The order of filling electrons in orbitals in increasing order are as follows- 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f 6d 7p.
7. s orbitals are spherical and possess a maximum of two electrons.
8. p orbital has a dumbbell-like shape and has three orbitals that are${\mathrm{p}}_{\mathrm{xy}},{\mathrm{p}}_{\mathrm{yz},}{\mathrm{p}}_{\mathrm{zx}}$. Each possesses two electrons so in total p orbital can possesses six electrons.

9. d orbitals have five orbitals four of them have clove-like shapes and one has a different shape than the others. These five orbitals are${\mathrm{d}}_{\mathrm{xy}},{\mathrm{d}}_{\mathrm{yz}},{\mathrm{d}}_{\mathrm{zx},}{\mathrm{d}}_{{\mathrm{x}}^{2-}{\mathrm{y}}^2}\mathrm{and}{\mathrm{d}}_{{\mathrm{z}}^2}$.
