Verified step by step guidance1
Recall the basic structure of an atom: it consists of protons, neutrons, and electrons.
Understand that protons carry a positive charge, neutrons are neutral (no charge), and electrons carry a negative charge.
Recognize that the number of protons in an atom's nucleus defines the element's chemical identity (its atomic number).
Note that neutrons do not carry a positive charge; they are neutral particles that contribute to the atom's mass but not its charge.
Remember that electrons are located in the electron cloud surrounding the nucleus, not inside the nucleus itself.
