Protons:
Sodium atoms always contain 11 protons in their nucleus. Protons are positively charged particles.
Neutrons:
Most sodium atoms also contain 12 neutrons in their nucleus. Neutrons are neutral particles, meaning they have no charge.
Electrons:
Sodium atoms have 11 electrons orbiting the nucleus. Electrons are negatively charged particles that orbit the nucleus in energy levels or electron shells.
The structure of a sodium atom can be represented as follows:
Protons: 11
Neutrons: 12
Electrons: 11
The atomic number of sodium is 11, which corresponds to the number of protons in the nucleus. The mass number of sodium is typically 23, which is the sum of its protons and neutrons.
