Question

atoms are usually electrically neutral, but they can lose or gain . electrically charged atoms or molecules are called .

electrons ions

Explanation:

Identify the subatomic particle involved in chemical bonding and charge changes

Atoms consist of protons, neutrons, and electrons. Protons and neutrons are bound tightly in the nucleus, whereas electrons reside in the outer shells and can be lost or gained during chemical interactions to form charged species. Therefore, the first blank is "electrons".

Define the term for charged atoms or molecules

When an atom or molecule loses or gains electrons, it acquires a net electrical charge. A charged atom or molecule is defined as an ion. Therefore, the second blank is "ions".

Answer:

Atoms are usually electrically neutral, but they can lose or gain <blank>electrons</blank>. Electrically charged atoms or molecules are called <blank>ions</blank>.
