Question

Is beryllium trivalent?​

Answer 1

Answer:

Explanation:

Beryllium is a chemical element with symbol Be and atomic number 4. ... As a free element it is a steel-gray, strong, lightweight and brittle alkaline earth metal. Beryllium improves many physical properties when added as an alloying element to aluminium, copper (notably the alloy beryllium copper), iron and nickel

Answer 2

No, Beryllium has valency +2.

This is because it has electronic configuration (2,2) so it looses two electrons to complete it's duet and form beryllium anion capable of forming compounds with other ions
