Orbital 'fill up' of Oxygen (atom number 8)
(K) = 2 electrons
(L) = 6 electrons
It is the electron configuration of a neutral, not excited atom.
1s2 2s2 2p4
When an electron is acquired by a neutral atom, the energy change is called electron affinity. Neutral atoms with an s2p6 electron configuration in the highest energy level are best classified as gases.
The arrangement of the electrons in an atom is known as its electron configuration.
This is obviously the Nobel gas argon.
The electron configuration for neutral Chlorine is 2.8.6.
It is the electron configuration of a neutral, not excited atom.
The ground-state electron configuration for a neutral atom of manganese is: 1s22s22p63s23p63d54s2 or [Ar]3d54s2
Calcium has the electron configuration [Ar]4s2; the neutral atom of calcium has 20 electrons.
13Al = 1s2,2s2,2p6,3s2,3p1
1s2,2s2,2p6,3s2,3p3
1s2 2s2 2p4
A neutral sodium must lose one electron in order for the resulting sodium ion to have the same electron configuration as an atom of the element neon.
A neutral atom, it only becomes an ion after it loses or gains an electron.
1s2 2s2 2p4
2, 6 or 1s2, 2s2, 2p6
The ions of elements nitrogen (N3-), oxygen (O2-), and fluorine (F-) will have the same electron configuration as a sodium ion (Na+), which is the same as the electron configuration of the noble gas neon.
