Verified step by step guidance

Understand that an atom consists of a nucleus and an electron cloud. The nucleus is the central part of the atom.

Identify the subatomic particles: protons, neutrons, and electrons. Protons and neutrons are located in the nucleus, while electrons orbit around the nucleus.

Recognize that protons are positively charged particles, and they contribute to the atomic number of an element.

Note that neutrons are neutral particles, meaning they have no charge, and they contribute to the atomic mass along with protons.

Understand that electrons are negatively charged particles, but they are not located in the nucleus; they are found in the electron cloud surrounding the nucleus.
