4. What is an electron configuration?  An electron configuration shows the distribution of electrons of an atom or a molecule. There is a specific notation that can quickly show you where the electrons are likely to be located, so knowing this notation is an essential part of knowing electron configurations. Reading these notations can tell you what element you’re referring to and how many electrons it has. [1] The structure of the periodic table is based on electron configuration. For example, the notation for Phosphorus (P) is {\ displaystyle 1s^{2}2s^{2}2p^{6}3s^{2}3p^{3}}.

5. What are electron shells? The area that surrounds the nucleus of an atom, or the area where the electrons orbit, is called an electron shell. There are usually around 3 electron shells per atom, and the arrangement of these shells is called the electron configuration. All electrons in the same shell must have the same energy. [2] Electron shells are also sometimes referred to as energy levels.

6. What is an atomic orbital?   As an atom gains electrons, they fill different orbitals sets according to a specific order. Each set of orbitals, when full, contains an even number of electrons. The orbital sets are: [3] The s orbital set (any number in the electron configuration followed by an "s") contains a single orbital, and by Pauli's Exclusion Principle, a single orbital can hold a maximum of 2 electrons, so each s orbital set can hold 2 electrons. The p orbital set contains 3 orbitals, and thus can hold a total of 6 electrons. The d orbital set contains 5 orbitals, so it can hold 10 electrons. The f orbital set contains 7 orbitals, so it can hold 14 electrons. The g, h, i and k orbital sets are theoretical. No known atoms have electrons in any of these orbitals. The g set has 9 orbitals, so it could theoretically contain 18 electrons. The h set would have 11 orbitals and a maximum of 22 electrons, the i set would have 13 orbitals and a maximum of 26 electrons, and the k set would have 15 orbitals and a maximum of 30 electrons. Remember the order of the letters with this mnemonic: [4]  Sober Physicists Don't Find Giraffes Hiding In Kitchens.

7. What are overlap orbitals? Sometimes, electrons occupy a shared orbital space. Take the Dihydrogen molecule, or H2. The 2 electrons must stay close to each other in order to stay attracted to each other and connect. Since they’re so close, they will occupy the same orbital space, thus sharing the orbital, or overlapping it. [5] In your notation, you’d simply change the row number to 1 less than it actually is. For example, the electron configuration for germanium (Ge) is {\ displaystyle 1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{2}.} Even though you go all the way to row 4, there is still a “3d” in the middle there because of overlap. [6]

8. How do you use an electron configuration table?   If you’re having trouble visualising your notation, it can be useful to use an electron configuration table so you can actually see what you’re writing. Set up a basic table with the energy levels going down the y-axis and the orbital type going across the x-axis. From there, you can draw your notation in the corresponding spaces as they go down the y-axis and across the x-axis. Then, you can follow the line to get your notation. [7] For example, if you were writing out the configuration for beryllium, you’d start up at the 1s, then loop back around to the 2s. Since beryllium only has 4 electrons, you’d stop after that, and get your notion of {\ displaystyle 1s^{2}2s^{2}.}
