Video answer: Electron configuration with noble gas notation
Top best answers to the question «Noble gas notation»
- For example, the electron notation of phosphorus is 1s 2 2s 2 2p 6 3s 2 3p 3, while the noble gas notation is [Ne] 3s 2 3p 3. This more compact notation makes it easier to identify elements, and is shorter than writing out the full notation of atomic orbitals.

As a result of a full shell, the noble gases can be used in conjunction with the electron configuration notation to form the noble gas notation. To do this, the nearest noble gas that precedes the element in question is written first 2 2
Symbol, group/series/block and Comments 1 Hydrogen, H 1s1 1s H, no Gp really, a bit unique! 2 Helium, He 1s2 = [He] 1s very stable, unreactive He, Gp 0/18 Noble Gas, 3 Lithium, Li 1s22s1 (simple notation: 2.1) [He]2s2p empty sub-shell Li,
A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons. So for sodium, we make the substitution of [Ne] for the 1 s2 2 s2 2 p6 part of the configuration. Sodium’s noble gas configuration becomes [Ne]3 s1.
Quick video on how to write an electron configuration for a specific element using Noble Gas notation.
Noble Gas notation helps simplify writing out electron configurations and the concise form makes locating an element when given the electron configuration easier. Write the electron configuration of the element oxygen atoms.
The noble gas you will use will be located in period three. Below is a list of the noble gases and their periods: 1: Helium 2: Neon 3: Argon 4: Krypton 5: Xenon 6: Radon For example, sodium is in period three. We will use neon for
the noble gas notations are the electronic configuration of an element ( the amount of electrons that this element has ) but using as a reference the electronic configuration of the last noble gas of the previous Row.
What is the noble gas notation of scandium? Look up the electronic configuration of that noble gas and include that value before the rest of the configuration….List of Electron Configurations of Elements. How do you write
