Question

the diagram below is an example of an atomic model. in this model, a positive electrical charge is shown with the plus symbol (+) and a negative electrical charge is shown with the minus symbol (-).
use the words below to label each part of the model.
electron proton atom neutron

Explanation:

1. The negatively charged (-) particles orbiting the central nucleus are electrons.
2. The positively charged (+) particles in the central nucleus are protons.
3. The uncharged (no symbol) particles in the central nucleus are neutrons.
4. The entire structure (nucleus + orbiting electrons) is the atom.

Answer:

• The outer (-) labeled particles: electron
• The central (+) labeled particles: proton
• The central unlabeled particles: neutron
• The entire circular structure: atom
