- Protons are positively charged particles that reside in the nucleus.
- Neutrons are particles with no electric charge that are found in the nucleus.
- The number of neutrons and protons in the nucleus can vary to form different elements.
Electron Configuration
- Electrons are smaller particles that surround the nucleus.
- Electrons are negatively charged particles that orbit the nucleus.
- The number of electrons in an atom is equal to the number of protons, ensuring the atom is electrically neutral.
