Writing Condensed/Abbreviated Electron Configuration for Carbon (C)

Показать описание
To write condensed electron configurations (also called abbreviated electron configurations) Carbon (C) we first write the full electron configuration for the element. Once we have the full configuration we put brackets around the config for the Noble Gas core. We can then replace this with the element symbol for the Noble Gas, leaving the rest of the configuration visible (these are the valence electrons).

For example, for Carbon, atomic number 6 on the Periodic Table:

Carbon 1s2 2s2 2p2 (full)
Carbon [1s2] 2s2 2p2 (Noble Gas in brackets)
Carbon [He] 2s2 2p2 (Condensed config)

For help writing electron configurations for elements:

The condensed electron configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. It places an emphasis on the valence electrons (the electrons written after the Noble Gas core). This makes it easier to understand and predict how atoms will interact to form chemical bonds.

hello doctor B. sorry for the bad english. I had a question for you. I want to know which computer programs you use. drawing, video montage and chemistry 3d models etc. Is it possible for you to list them all? I am waiting for your return. thanks in advance

Could someone please explain if negative (periodic) ELEMENTS exist and if they are regarded as dark matter or some other matter?
