beryllium (Be)
The element you are referring to is beryllium (Be). Beryllium is an alkaline Earth metal that has two electrons in the second energy level.

Beryllium is the alkaline earth metal that has 2 valence electrons.
You mean valence electron? 2 If your talking about Bohr Diagrams then it depends on the metal
The alkaline earth metals are those in the same group as calcium; they have two valence electrons.
alkaline earth metals such as Be, Mg, Ca, Sr, Ba, Ra
None. The alkaline earth metals have a valance of 2 and the 6A nonmetals have a valance of 6. So the alkaline earth's donate two electrons and the 6A's accept 2 electrons. MgO CaS by example
An alkaline earth metal would typically lose two electrons to become stable. This would result in the metal forming a 2+ cation, as it will have the same electron configuration as the nearest noble gas.
The outermost shell contains two electrons.
The valence shell of magnesium (Mg) contains 2 electrons in the outermost energy level. This is because magnesium is an alkaline earth metal with 2 valence electrons. These electrons are located in the 3s orbital in the third energy level.
Alkaline-earth metal ions typically have a charge of +2. This is because they lose two electrons to achieve a stable electron configuration, resulting in a 2+ charge. Examples of alkaline-earth metals include calcium (Ca2+), magnesium (Mg2+), and barium (Ba2+).
