Beryllium would have that configuration
There are a total of 14 electrons in this electron configuration. The element whose atomic number corresponds to 14 is silicon.
Nitrogen has 7 protons and thus 7 electrons to be neutral. It's total configuration is 1s2 2s2 2p3. Therefore, its valence configuration is 2s2 2p3.
The electron configuration for a fluorine ion (F-) is 1s2 2s2 2p6, which is equivalent to the neon noble gas electron configuration. This is because the fluorine ion gains one electron to achieve a stable octet configuration similar to a noble gas.
Fluorine's atomic number is 9. Thus, neutral fluorine has 9 protons and 9 electrons. It's total configuration then is 1s2 2s2 2p5, so its valence configuration is 2s2 2p5.
Chlorine has seven valence electrons. The electronic configuration is 1s2, 2s2, 2p6, 3s2, 3p5. These seven valance electrons do NOT readily react, because they are 'tightly' held to the nucleus. However, chlorine has strong electron affinity; Electronegativity; this means it will attract one electron into its valance shell , to complete the octet of eight electrons in the valance shell. When this 'extra' electron combines into to valance shell , the electron configuration is 1s2, 2s2, 2p6, 3s2, 3p6. , and the chlorine atom is now a 'CHLORIDE ANION' of charge '-1' , (symbolised by Cl^(-)).
The electron configuration of beryllium is written as [He] 2s2. This means that it has 2s2 electrons above the configuration of Helium.
The element with the electron configuration 1s2 2s2 2p6 is neon (Ne).
1s2 2s2 2p6 3s2 3p3 is the electron configuration of element 15.
Bromine has 7 electrons in its fourth energy level.
This group has the electron configuration of sulfur. The element sulfur has 16 electrons, and its electron configuration is 1s2 2s2 2p6 3s2 3p4.
The valence electron configuration of oxygen is 2s2 2p4. Oxygen has 6 valence electrons in total, with 2 in the 2s orbital and 4 in the 2p orbital.
The element with the electron configuration 1s2 2s2 2p6 3s2 3p6 is Argon, which has an atomic number of 18.
The most electronegative element is fluorine. Its electron configuration is 1s2 2s2 2p5.
There are a total of 14 electrons in this electron configuration. The element whose atomic number corresponds to 14 is silicon.
Magnesium
The element with the electron configuration of 2s2 2p4 is Oxygen (O), which has 8 electrons in total.
Phosphorus has the above electron configuration. It has 15 electrons and protons.
