Answer:

Be²⁺: 1s²

Explanation:

The electron configuration is as follows:

Be: 1s²2s²

Be²⁺: 1s²

Be²⁺ ion has two electrons in the first shell. This is a stable electron configuration. The other stable electron configuration is an octet where there are eight valence electrons.  

The electron configuration of Be²⁺ is the same as that of He (helium). Helium is a noble or inert gas.  

Be²⁺ = He = 1s²

It will be the core of the atom surrounded by one electron cloud with two electrons the second electron cloud with the two other electrons will be omitted because those electrons were lost to give it a positive charge. electrons and protons come in equal numbers at most ground states and that is why. For periodic table however the proton count will always be the same count as the electrons.
