Answer: Orbitals are the regions of space in which electrons are most likely to be found. Explanation: Each orbital is denoted by a number and a letter. The number denotes the energy level of the electron in the orbital. Thus 1 refers to the energy level closest to the nucleus; 2 refers to the next energy level further out, and so on.

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.
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). (image source) So for example, a hydrogen atom with one electron would be denoted as $\ce{1s^1}$ - it has one electron in its 1s orbital
14 Αυγ 2020 · Orbitals with \(\ell = 1\) are p orbitals and contain a nodal plane that includes the nucleus, giving rise to a dumbbell shape. Orbitals with \(\ell = 2\) are d orbitals and have more complex shapes with at least two nodal surfaces.
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.
So when we say 1s or 3d xz we are orbital in terms of its location in space, and the images in Figure \(\PageIndex{1}\) represents the shapes of some common orbitals where there is roughly a 90% probability of finding the electron that resides in that orbital.
23 Σεπ 2024 · An s orbital is spherical, a p orbital is dumbbell-shaped, and four of the five d orbitals are cloverleaf-shaped. Different lobes of p orbitals are often drawn for convenience as teardrops, but their actual shape is more like that of a doorknob, as indicated.
