Biology our body sends electrical messages throughout our body using charged atoms. these charged atoms have either a positive or negative charge because they either gained or lost electrons. what are these charged atoms called? question 7 options: a.) ions b.) covalents c.) organic molecules

Option (a) is the correct answer.

Explanation:

When a neutral atom loses an electron then it acquires a positive charge.

For example, sodium on losing an electron become ion.

On the other hand, if a neutral atom gains an electron then it acquires a negative charge.

For example, a neutral chlorine atom on gaining an electron forms .  

Hence, an ion is formed in both the cases.

Thus, we can conclude that in the given situation these charged atoms called ions.
