Question

What Be will form Cation or anion​

Answer 1

Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. ... The alkaline earth metals (IIA elements) lose two electrons to form a 2+ cation. Aluminum, a member of the IIIA family, loses three electrons to form a 3+ cation.

Answer 2

"Answer:

Be forms a cation, $Be^{2+}$

Explanation:

It has an electronic configuration=$1s^2 2s^2$ or 2,2

It is easier for Be to donate 2 electrons to attain the nearest noble gas configuration which is of Helium.
