There are four electrons in a Beryllium atom. Hence the mono positive ion has only three electrons. Therefore the electron configuration is 1s2 2s1.
Beryllium electron configuration is [He]2s2.
The electron configuration of beryllium is: 1s22s2. The atomic weight (not mass) of beryllium is 9,012 183(3).
Electronic configuration of beryllium: 1s2.2s2.
The electron configuration of Cu2+ is [Ar]3d94s0.
Cobalt(II) electron configuration is [Ar]3d7.
The electron configuration of beryllium is written as [He] 2s2. This means that it has 2s2 electrons above the configuration of Helium.
