Question

What is the value of SPDF?

Answer 1

Hint :The orbital names s, p, d, and f refer to groups of lines that were first observed in the spectra of alkali metals. Sharp, principal, diffuse, and fundamental are the four line groups. For the s, p, d, and f subshells, the azimuthal quantum numbers are 0, 1, 2, and 3, respectively.

Complete Step By Step Answer:
The s subshell can hold two electrons, while the p subshell can hold six, the d subshell can hold ten, and the f subshell can hold fourteen.
The s orbitals are circular, whereas the p orbitals are polar and oriented in specific directions (x, y, and z). It might be easier to think of these two letters as orbital shapes (d and f aren't as easily described). The cross-section of an orbital, on the other hand, is not uniform.
The distribution of electrons among available shells is referred to as an atom's electron configuration. An electron can be anywhere at any given time, but it's most likely contained somewhere within the volume described by the orbital shape. Only by absorbing or emitting a packet or quantum of energy can electrons move between orbitals.
Electrons have a predictable way of filling up energy levels. The pattern for electron filling is as follows:
1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f
2 electrons can be held in s.
6 electrons can be held by p.
d has a capacity of 10 electrons.
f has a capacity of 14 electrons.

Note :
There are shells with higher and lower electron density for the s orbital, for example. Near the nucleus, the density is extremely low. However, because it isn't zero, there is a chance of finding an electron within the atomic nucleus.
