Question

when electrons are removed from the outermost shell of a calcium atom, the atom becomes an anion that has a larger radius than the atom. an anion that has a smaller radius than the atom. a cation that has a larger radius than the atom. a cation that has a smaller radius than the atom.

Explanation:

Cuando se remueven electrones de un átomo, este adquiere una carga positiva y se convierte en un catión. Además, al remover electrones, la atracción nuclear sobre los electrones restantes es mayor, lo que reduce el radio atómico.

Answer:

a cation that has a smaller radius than the atom.
