What are the 4 types of orbitals and how many electrons can each type hold

The s subshell is a spherical orbital which can contain up to two electrons. Each energy level has one s subshell.The p subshell has three dumbbell-shaped orbitals, arranged at right angles to each other. Each of these orbitals can contain up to two electrons, so a fully-filled p subshell will contain six electrons. The p subshell can be found in energy levels of two or higher.The d subshell has a set of five orbitals, arranged to lie along the x, y, and z planes. (The picture above really helps here.) Each of the five orbitals can contain up to two electrons, so a fully loaded d subshell will contain ten electrons. This subshell can be found in energy levels of three or higher.The f subshell has a set of seven orbitals, symmetrically distributed throughout the x, y, and z planes. Each of the seven orbitals can contain up to two electrons, for a total of fourteen electrons in a fully-stacked shell. This subshell can be found in energy levels of four or higher. Electrons are filled into these orbitals, up to two per orbital, starting from the lowest shell.
