Explanation:
The region x of the atom shown is called the nucleus of the atom shown. The nucleus of an atom contains protons and neutrons.
- Protons are the positively charged particles found in the nucleus
- Neutrons do not carry any charges.
- Together protons and neutrons determines the mass of the atom.
- The mass of an atom is concentrated in the nucleus
- Both particles have equal masses
The region y is the atomic orbital where electrons can be found.
