Guida verificata passo dopo passo1
Recall the three main subatomic particles in an atom: protons, neutrons, and electrons.
Understand the charge of each particle: protons have a positive charge, neutrons have no charge (neutral), and electrons have a negative charge.
Identify the location of each particle within the atom: protons and neutrons are located in the nucleus, while electrons orbit around the nucleus.
Recognize that alpha particles are composed of two protons and two neutrons, so they carry a positive charge but are not individual subatomic particles inside a single atom's nucleus.
Conclude that the subatomic particles with a positive charge found in the nucleus of an atom are protons.
