Explain what a noble-gas electron configuration is?

Answer 1

The noble gas notation is a notation formed as a result of the electron configuration notation being used in conjunction with noble gases. The noble gas preceding the element in question is written then the electron configuration is continued from that point onwards. The notation is shorter to write and makes it easier to identify elements. The noble gas notation starts for elements after helium.

For example, the electronic configuration of carbon is 1s2 2s2 2p2, whereas its noble gas notation is [He] 2s2 2p2.

Answer 2

The noble gas notation is a notation formed as a result of the electron configuration notation being used in conjunction with noble gases.

The noble gas preceding the element in question is written then the electron configuration is continued from that point forward.

Answer 5

"Noble gas configuration" means that in writing out an electron configuration for an atom, rather than writing out the occupation of each and every orbital specifically, you instead lump all of the core electrons together and designate it with the symbol of the corresponding noble gas on the Periodic Table (in brackets). For example, the noble gas configuration of nitrogen is [He]2s22p3

Answer 6

How to Change Electron Configuration to Noble Gas NotationWe will use Chlorine Cl as an example. Cl is number 17 on the Periodic Table of elements, so the configuration comes out to be

1s22s22p63s23p5

Once you have this, go to the first noble gas that comes before the element. In this case, the noble gas is Neon Ne (The noble gas you use is at the end of the period above the element). A period is each of the horizontal rows on the Periodic Table.

Write the Noble Gas' element. For Neon, this is Ne.

Since Neon is BEFORE the element Chlorine, it contains the SAME electron configuration, except that Chlorine has more electrons, therefore more orbitals filled up (a longer configuration). We take the segment of the "extra" configuration from Chlorine and attach it to the aforementioned Ne.

Attach it like this:

[Ne] 3s23p5
