unit 4l test 25 - 26\na beryllium (be²⁺) cation has\n - gained two electrons.\n - lost two protons.\n - gained two protons.\n - lost two electrons.

Answer

Brief Explanations:

Cations are positively - charged ions. They form when an atom loses electrons. A beryllium ($Be^{2 + }$) cation has a + 2 charge, which means it has lost two electrons. Protons are not gained or lost in the formation of simple ions under normal chemical conditions.

Answer:

lost two electrons
