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).
S orbitals have a spherical shape, p orbitals are dumbbell-shaped, d orbitals are shaped like a cloverleaf, and f orbitals are characterized by more complex shapes. You can also look up more detailed images for the shapes and orientation of atomic orbitals in your textbook.
An s orbital is spherically symmetric around the nucleus of the atom, like a hollow ball made of rather fluffy material with the nucleus at its centre. As the energy levels increase, the electrons are located further from the nucleus, so the orbitals get bigger. The order of size is 1s < 2s < 3s < …, as shown below.
While the concepts of electron shells and orbitals are closely related, orbitals provide a more accurate depiction of the electron configuration of an atom because the orbital model specifies the different shapes and special orientations of all the places that electrons may occupy.
7 Μαΐ 2019 · The orbital letters are associated with the angular momentum quantum number, which is assigned an integer value from 0 to 3. The s correlates to 0, p to 1, d to 2, and f to 3. The angular momentum quantum number can be used to give the shapes of the electronic orbitals.

14 Αυγ 2020 · An orbital is the quantum mechanical refinement of Bohr’s orbit. In contrast to his concept of a simple circular orbit with a fixed radius, orbitals are mathematically derived regions of space with different probabilities of containing an electron.
