The concept of subshells is not that complicated. When l=0 corresponds to the s subshell, l=1 corresponds to the p subshell, l=2 corresponds to the d subshell, etc. For instance, if n=3, l=0,1,2.Īs mentioned, these values can also tell us the shape of the orbitals. Values of l can range from 0 to n-1 and are always positive integers. The value of l depends on the value of n. This number has 2 functions – it states the subshell in which the electron can be found, and also gives us an idea of the shape of the orbital. These values start from 0 and keep increasing. Azimuthal Quantum Numberĭenoted by ‘ l’, this is also called the orbital angular momentum quantum number. The first shell, i.e., n=1 is called the ‘K’ shell, while n=2 is called the ‘L’ shell and so on and so forth. For Na, 1, 2 and 3 were the principal quantum numbers. In lieu of this, the first quantum number, or principal quantum number, denotes the number of the shell in which the electron can be found. These are arranged in increasing order, i.e., the shell closest to the nucleus has the lowest energy, which increases as it moves away from the nucleus. ![]() As we know, electrons can be arranged in different shells or energy levels. These are a set of 4 numbers that together define the position of each individual electron in the atom. ![]() Let’s try to understand what these are, and determine how to arrive at the electron configuration of an atom. Knowing the electron configuration of an atom can provide a lot of insight into its location on the periodic table, predict its behavior in reactions, its state, etc. The numbers and letters together give the address of each electron, so to speak. This is what a typical electron configuration of an element looks like : Na – 1s 2 2s 2 2p 6 3s 1 Therefore, electron configuration is honestly our best calculated guess as to where the electrons can be found. However, technically, it is impossible for us to state precisely where the electrons will be. The electron configuration of an atom is, in simple terms, the arrangement of electrons around the nucleus of that atom. ![]() The fourth quantum number, spin quantum number, gives information about the spin of the electron. The third quantum number, magnetic quantum number, gives information about the atomic orbital of the electron. The second quantum number, azimuthal quantum number, denotes the subshell in which the electron can be found. The first quantum number, or principal quantum number, denotes the number of the shell in which the electron can be found. Quantum numbers are a set of four numbers that define the position of each individual electron in an atom.
