Key Idea I The arrangement of electrons is distributed between four orbital’s; S, P, D and F. Each orbital is a different shape and holds a different number of electrons. Orbital S is a circle and it contains two electrons and orbital P has three different shells. One shell is an infinity sign, the next is a crooked infinity sign and the last is shaped like an upright infinity sign. Each shell can hold two electrons which allow orbital P to hold six electrons, orbital D can hold ten electrons, and orbital F can hold fourteen electrons. Key Idea II The Aufbau principal is used to determine the electronic configuration of an atom or an ion. According to the Aufbau Principal, in order to determine an element's ground state electron configuration is learning the sequence of …show more content…
The fact that negatively charged electrons repel each other has an important impact on the distribution of electrons in equal-energy orbitals. In order to represent an atom's electron configuration there is one method called an orbital diagram . Orbit ital diagram includes a space for each of the atoms orbitals. An empty space represents an unoccupied orbital. A space occupied with one up arrow represents an orbital with one electron. a space containing both an up and down arrow represents a filled orbital. Each box is labeled with the principal quantum number and sub level associated with the orbital. Sub level P has three spaces and is one behind, sub level D has five spaces and is two behind. Each line must have all up arrows before going through and adding down arrow. For example carbon's orbital diagram is (C) 1s2 contains both up and down arrows, along with 2s2. 2p2 contains two up arrows, leaving the last space blank and no down
