Answer:

Cr ^ 3 +

Explanation:

Recordemos que el número atómico es el número de protones en el núcleo del átomo. También corresponde al número de electrones en el átomo neutro.

Dado que el número de protones es 24, entonces el elemento debe ser cromo.

Si hay 21 electrones presentes, entonces se deben haber perdido 3 electrones para dar Cr ^ 3 +.
