Can you provide the structure of the atom?

The structure of an atom consists of a central nucleus containing protons and neutrons, surrounded by electrons orbiting the nucleus in specific energy levels or shells.

• Nucleus:
• Contains positively charged protons.
• Contains neutral neutrons.
• The nucleus accounts for almost all of the atom's mass.
• Electrons:
• Negatively charged particles.
• Orbit the nucleus in energy shells or levels.
• Much lighter than protons and neutrons.
• The number of electrons equals the number of protons in a neutral atom.

This arrangement is often visualized using the Bohr model or more complex quantum mechanical models.
