Recall the basic structure of an atom, which consists of three main subatomic particles: protons, neutrons, and electrons.
Understand the charges associated with each particle: protons carry a positive charge, neutrons have no charge (neutral), and electrons carry a negative charge.
Recognize that protons and neutrons are located in the nucleus, the central part of the atom, while electrons are found in the electron cloud surrounding the nucleus.
Since protons are positively charged and are located in the nucleus, the nucleus as a whole is positively charged due to the presence of protons.
Therefore, the part of the atom that is positively charged is the nucleus, because it contains the positively charged protons.
