Alkaline earth metals have 2 electrons in their outer shell.
The outermost shell contains two electrons.
Elements in the second group have 2 outer shell electrons and also very reactive. What are they called?
Magnesium has a total of 12 electrons. The electron configuration would be 1s2 2s2 2p6 3s2. Therefore, 2 electrons in it's outer shell.
Nitrogen has five electrons in its outer shell and bromine has seven in its outer shell.
Boron has three electrons in its outer shell
Vanadium has on the outer shell two electrons.
YEP! remember In science in order for the Alkali metals and Alkaline earth metals to become stable they must give AWAY electrons. The Earth metals have a Plus 2 charge because they give away 2 electrons on there outer shell!
An alkaline element in the ground state typically has 1 or 2 electrons in its valence shell. This is because alkaline elements belong to group 1 or 2 of the periodic table, which corresponds to 1 or 2 valence electrons.
You mean valence electron? 2 If your talking about Bohr Diagrams then it depends on the metal
No, helium has 2 electrons in its outer shell, while magnesium has 2 electrons in its outer shell. So, they do not have the same amount of electrons in their outer shell.
A neutral neon atom has 8 electrons in its outer shell. Neon has a total of 10 electrons, with 2 in the inner shell and 8 in the outer shell.
