The valence of beryllium is two.
The element with a valence electron configuration of 2s2 is beryllium. Beryllium has 4 electrons, with 2 in the 2s subshell, which makes it have a valence electron configuration of 2s2.
Beryllium has two valence electrons.
The electron configuration of beryllium is written as [He] 2s2. This means that it has 2s2 electrons above the configuration of Helium.
Beryllium has one valence shell containing two electrons.
Beryllium has two valence electrons.
Beryllium has four orbitals in its electron configuration.
Beryllium has two valence electrons.
The beryllium atom has 4 electrons and the valence is 2.
2
The valence level of beryllium is 2. This means that in its neutral state, beryllium has 2 valence electrons.
Beryllium has 4 electrons.
In the electron dot structure for beryllium fluoride (BeF2), beryllium has 2 valence electrons and fluorine has 7 valence electrons. Beryllium will share its 2 electrons with 2 fluorine atoms, resulting in a Be-F bond with each fluorine. This forms a linear molecular shape with beryllium in the center and two fluorine atoms on either side.
