Question

an element has an atomic number of 16. an ion of this element has a 2 - charge. how was the ion formed? (1 point) a neutral atom gained 2 electrons. a neutral atom lost 2 electrons. a neutral atom gained 16 electrons. a neutral atom lost 16 electrons.

Explanation:

Step1: Understand ion - charge concept

An ion with a 2 - charge means it has an excess or deficiency of 2 electrons compared to a neutral atom. A negative charge indicates an excess of electrons.

Step2: Analyze the options

A neutral atom that gains electrons becomes a negatively - charged ion. Since the ion has a 2 - charge, it means the neutral atom gained 2 electrons.

Answer:

A. A neutral atom gained 2 electrons.
