Ответ:
The atomic number of the element Radium (Ra) is 88. It is an alkaline earth metal. Electronic configuration of Radium (Ra) will be![[Rn]7s^{2}](/tpl/images/0048/1494/91ed0.png)
It belongs to the group IIA of the periodic table. Alkaline earth metals that belong to the group IIA of the periodic table lose the valence electrons to form a +2 ion.
Therefore, Radium with an electronic configuration of![[Rn]7s^{2}](/tpl/images/0048/1494/91ed0.png)
will lose the two 7s electrons to form the cation with +2 charge.
