Mercury has 2 electrons in its outer level, which is the 6th and final energy level for mercury.
There are no unpaired electrons in an unexcited neutral mercury atom; its outer shell contains only two s electrons that are paired, as are all the electrons in the filled inner shells of the atom.
An element that has two outer electrons is carbon. Carbon would not use the energy to gain six more electrons when it can easily get rid of the two outer electrons.
Yes, barium is divalent with two electrons in the outer shell.
Calcium has two electrons in the outer shell.
Vanadium has on the outer shell two electrons.
Two electrons
Beryllium has one outer electron shell with two electrons.
Uranium has 2 electrons on its outer energy level.
Magnesium has 2 electrons on its outer energy level.
The alkaline earth metals (group 2 on the periodic table) have two valence electrons (electrons in their outer level).
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
