A wave function for an electron in an atom is called an atomic orbital. Nevertheless, these orbitals represent the regions in which an electron with the energy of a d orbital are most likely to be found. Note that each sp orbital contains one lobe that is significantly larger than the other. P orbitals have 3 different rotations along the x y and z axes. All orbitals are computed using the hydrogenic equations, but any atom can be specified by giving the number of protons sometimes referred to as z, and the atomic.

A powerpoint modelling orbitals and introduce electron configuration in different elements, requires an understanding of discrete energy levels in atoms already. Atomic orbitals are regions in space where the electron is most likely to be found. At the fourth and higher levels, there are seven f orbitals in addition to the 4s, 4p, and 4d orbitals. Questions, suggestions, and bug reports are all welcome.
Two pairs of parallel p orbitals can overlap as shown in b and c, and the third pair can overlap headon as shown in d. It explores s and p orbitals in some detail, including their shapes and energies. The forbitals, on the other hand, are not so familiar. Each orbital, no matter what the type, can only hold 2 electrons. The simple names s orbital, p orbital, d orbital, and f orbital refer to orbitals with angular momentum quantum number. For example, on any level, a p sublevel is actually made up of a group of three orbitals. While the shapes of many of the d sub orbitals are reminiscent of the p orbitals, they are different.
