Answer:
Beryllium has an electronic configuration of 1s2 2s2 in its natural state. When in an ion state of Be2+ it loses the electrons in a 2s shell and has a configuration of 1s2. This means that Be2+ has 2 electrons.
The best and most correct answer among the choices provided by your question is the second choice.
<span>Based on the reaction given above, as the temperature decreases, the formation of the reactants will increase.</span>
