Orbital 'fill up' of Oxygen (atom number 8)
(K) = 2 electrons
(L) = 6 electrons
The electron configuration for oxygen is 1s2 2s2 2p4. This represents the distribution of electrons in the energy levels and sublevels of the oxygen atom.
The electron configuration for a nitrogen anion with a charge of -2 (N²⁻) involves adding two additional electrons to the neutral nitrogen atom. The neutral nitrogen atom has an electron configuration of 1s² 2s² 2p³. Therefore, the electron configuration for the N²⁻ ion is 1s² 2s² 2p⁵.
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 fluoride ion has the same electron configuration as a neon atom. This is because fluoride has gained an extra electron compared to a neutral fluorine atom, resulting in a full valence shell with 8 electrons. Therefore, the electron configuration of a fluoride ion is 1s2 2s2 2p6.
This is obviously the Nobel gas argon.
The electron configuration of oxygen in the oxide ion (O2-) is 1s2 2s2 2p6 (equivalent to the configuration of a neon atom), as the oxide ion has gained two extra electrons compared to a neutral oxygen atom.
Calcium has the electron configuration [Ar]4s2; the neutral atom of calcium has 20 electrons.
The ground-state electron configuration for a neutral atom of manganese is: 1s22s22p63s23p63d54s2 or [Ar]3d54s2
The electron configuration for a neutral atom of chlorine is 1s2 2s2 2p6 3s2 3p5. Chlorine has 17 electrons, and this configuration indicates the distribution of those electrons in its various energy levels.
The electron configuration for a neutral potassium atom is 1s2 2s2 2p6 3s2 3p6 4s1. This configuration represents the arrangement of electrons in the energy levels around the nucleus of the potassium atom.
13Al = 1s2,2s2,2p6,3s2,3p1
The electrons configuration for O2- is [He]2s22p6.
The electron configuration for oxygen is 1s2 2s2 2p4. This represents the distribution of electrons in the energy levels and sublevels of the oxygen atom.
A neutral sodium atom must lose one electron to have the electron configuration of neon, which has a stable electron configuration with a full outer shell. Sodium typically forms a +1 cation by losing this one electron to achieve a stable configuration like neon.
The electron configuration for a nitrogen anion with a charge of -2 (N²⁻) involves adding two additional electrons to the neutral nitrogen atom. The neutral nitrogen atom has an electron configuration of 1s² 2s² 2p³. Therefore, the electron configuration for the N²⁻ ion is 1s² 2s² 2p⁵.
A neutral atom, it only becomes an ion after it loses or gains an electron.
The electron configuration for a neutral atom of phosphorus is 1s2 2s2 2p6 3s2 3p3. This means phosphorus has 15 electrons distributed among its energy levels.
