Magnesium, Mg.
None - that's a compound, not an element.
14 electrons makes this element silicon.
Silicon.Neon has 10 electrons. Adding 4 more electrons to that gives 14 electrons, and the configuration of [Ne] 3s2 3p2. This configuration belongs to the element silicon.
That would be silicon.
That doesn't exist ^^ Either you may mean: 1s2 2s2 2p6 3s2 3p2 >>Silicon 1s2 2s2 2p6 3s2 >> Magnesium
Aluminium
There are a total of 14 electrons in this electron configuration. The element whose atomic number corresponds to 14 is silicon.
3 and p2 are both factors of each part of the binomial, so divide it from each part and see what you have left. (3p4 / 3p2) - (12p2 / 3p2) (3p2)(p2-4)◄
Silicon has the electron configuration of 1s2 2s2 2p6 3s2 3p2. The abbreviated form is [Ne] 3s2 3p2.
Silicon
The electron configuration of Si is 1s2 2s2 2p6 3s2 3p2. Using the noble gas shortcut, this is written [Ne] 3s2 3p2.
