Explanation:
Beryllium is a group 2 element and its atomic number is 4. Electronic configuration of beryllium is .
Since, a beryllium contains two valence electrons so, in order to attain stability it will readily lose its 2 valence electrons.
Therefore, a beryllium atom upon losing two valence electrons will acquire a +2 charge.
Thus, we can conclude that the net ion charge of Beryllium is +2.
Explanation:
elements are based on electrical conductivity
