S, P, D, F are the orbital and orbitals are known as the regions of space where electrons exist. Here each of the orbitals is denoted by a specific number and letter. The numbers are known for identifying the energy levels of the electron in a given orbital as 1 refers to the energy that is seen to be the closest to the nucleus. Naming the letters like S, P, D, F is purely historical.

The Orbital S is known to be spherical around the nucleus of an atom, and the P orbital points only a specific direction, Coming to d there are 5 orbitals, and finally, f has seven orbitals.

 It is impossible to show the orbital pictorially, but we can assume the shape of how an electron is seen., which is not a 100 per cent accurate.

Hope this helps

S= Sharp P= Principal D= Diffuse F= Fundamental S, p,d,f are the names of subshells within a shell whose values are determined by azimuthal quantum number. Their respective azimuthal quantum numbers are 0, 1, 2 and 3. These terminologies are adopted from Spectroscopic analysis of matters.

s, p, d, f and so on are the names given to the orbitals that hold the electrons in atoms. These orbitals have different shapes (e.g. electron density distributions in space) and energies (e.g. 1s is lower energy than 2s which is lower energy than 3s; 2s is lower energy than 2p).

The orbitals are of 4 types. They are named s,p,d,f .The s, p, d, and f stand for sharp, principal, diffuse and fundamental, respectively. The letters and words refer to the visual impression left by the fine structure of the spectral lines which occurs due to the first relativistic corrections, especially...

The orbitals are of 4 types. They are named s,p,d,f .The s, p, d, and f stand for sharp, principal, diffuse and fundamental, respectively. The letters and words refer to the visual impression left by the fine structure of the spectral lines which occurs due to the first relativistic corrections, especially the spin-orbital interaction. Technically speaking, an orbital is a wave function for an electron defined by the three quantum numbers, n, ? and ml. What the wave function describes, though, is a region in space with a particular shape, where you are likely to find an electron. In terms of waves, the orbital describes the region in space where the electron density is very thick. In terms of particles, the orbital describes the region in space where there is a high probability of finding the electron (which should make sense, because wherever the electron density is thick, there is also a high probability of finding the electron). read less

these are the classification of modern periodic tableand can be understand by electronic configuration . as s shell occupies 2 electron so have 2 block . p=6,d=10
