A. The protons and neutrons are located in the core area and the
electrons are located in the peel.
Explanation:
At the core of the apple which is the middle of the apple, the protons and neutrons would be found there.
The peel area would be dominated by the electrons.
The orbital model of the atom suggests that an atom is made up of three fundamental subatomic particles.
- The protons and neutrons are the most massive particles at the center of the atom. They occupy a tiny space at the core of the atom.
- The electrons are revolving round this center in specific energy levels.
- This would be the peel area of the apple.
