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.

Um google the question and answer them.
