1) Label the particles X, Y and Z from the diagram of the model of the atom below

Particle X represents Protons
Particle Y represents Electrons
Particle Z represents Neutrons
An atom consist of three subatomic particles which are
In the nucleus of an atom, we have the proton and neutron. Protons are positively charged while neutrons have no charge.
Electrons are located outside the nucleus and are negatively-charged.
In the given diagram,
X has a positive charge which indicate that X represents protons.
Z is in the nucleus of the atom, and has no charge. This indicates that Z represent neutrons.
Y is located outside of the nucleus, thus, Y represents electrons.
Hence,
Particle X represents Protons
Particle Y represents Electrons
Particle Z represents Neutrons
