To help describe the appropriate notation for electron configuration, it is best to do so through example. In this video we will write the electron configuration for F-, the Fluoride ion. So an atom with 3 electrons will have 2 electrons in the K shell and the third electron goes into the 2nd energy level (L shell): The electron configuration (electronic configuration) of the atom is 2,1 If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. Since K loses one electron (1 negative charge) it is no longer neutral; it now has a +1 charge. Correct Answer: 3. What we will do now is place those electrons into an arrangement around the nucleus that indicates their energy and the shape of the orbital in which they are located. K shell is full because the K shell can only hold 2 electrons, so the next electron must be positioned in the next energy level (next shell). For example, the electron configuration of lithium, 1s²2s¹, tells us that lithium has two electrons in the 1s subshell and one electron in the 2s subshell. Periods 1 to 3: Subshell Electronic Configuration Key Concepts. Since 1s can only hold two electrons the next 2 electrons for Potassium go in the 2s orbital. For this example, we will use the iodine atom. To form K+1we remove electron. Energy of electrons increases as they get further away from the nucleus. 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f For atoms with more than 3 electrons, we can continue adding electrons to the second energy level or L shell until it reaches its maximum capacity of 8 electrons: 1s2 2s2 2p6 3s2 3p6 Comment to Instructor: Choice 1 is the e-config. So instead of talking about "shells" we can also talk about energy levels: And now we can draw the energy levels only, without drawing the rest of the circle to represent the shell: And, we can now see an ever shorter way to represent the electronic structure of an atom, we can just write down how many electrons are present in each shell (energy level) separated by a comma, and this shorthand is referred to as the electron configuration or electronic configuration of the atom. 1. Electrons of atoms of period 2 elements had a completed first energy level (K shell) and were filling up the second energy level (L shell), which was completed by the last member of the period, neon.

Electrons closest to the nucleus, in the K shell, have less energy than electrons in the next shell out from the nucleus, the L shell. Therefore, the number of electrons in an atom of an element is equal to the element's atomic number (Z): But the atomic number (Z) only tells us how many electrons in total there are around the nucleus of a neutral atom, it doesn't directly tell us how those electrons are arranged around the nucleus. For example, the s sublevel can only hold two electrons, so the 1s is filled at helium (1s 2).The p sublevel can hold six electrons, the d sublevel can hold 10 electrons, and the f sublevel can hold 14 electrons. K loses an electron so that it will have the same electron configuration as Ne. Potassium is already done as an example for you. The elements of the first three periods of the periodic table are shown below: There are only two elements in period 1 of the periodic table; hydrogen and helium: An atom of hydrogen only has 1 electron, so this electron occupies the K shell (first energy level), and its shell electron configuration is simply 1 Period 1: K shell (1 st energy level) filling Period 2: … Remember a set of numbers identifies the electron, where it's located, and what it's doing. Electron configuration for aluminium is 2.8.3; Valence electrons: 3 . Potassium(1+) is a monoatomic monocation obtained from potassium.It has a role as a human metabolite and a cofactor.
