Based on the ionic notation shown here, what has happened to this ion. Be2+ Select the 2 correct answers.
*
Atom has become an anion.
Atom has become a cation.
Atom has lost 2 electrons.
Atom has gained 2 electrons.

Atom has become a cation.

Atom has lost 2 electrons.

Explanation:

Based on the ionic notation of the element or ion given, we can clearly state that the atom has become a cation and it has lost two electrons.

A cation is an atom that has lost electrons to become positively charged.

In a neutral atom, the number of protons and electrons are the same.

Protons are the positively charged particles within an atom.

Electrons are the negatively charged particles.

 When an atom loses electrons, it becomes positively charged because the number of electrons is now more.

Positively charged atoms are called cations.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
