Structure of an Atom

Atoms are the fundamental building blocks of matter, including elements like aluminum.

Aluminum (Al) is a metallic element known for its lightweight, corrosion resistance, and malleability.
It has several important physical and chemical properties:
- Lightweight: Aluminum is less dense compared to many metals, making it ideal for applications where weight savings are important (e.g., aerospace).
- Corrosion Resistance: It forms a thin layer of aluminum oxide on its surface, preventing rusting and enhancing durability in various environments.
- Malleability and Ductility: Aluminum can be easily shaped and stretched without breaking, allowing for a wide range of applications in construction and manufacturing.
- Conductivity: While it does not conduct electricity as well as copper, aluminum is still used in many electrical applications due to its conductivity and lightweight nature.

The atom is composed mainly of three subatomic particles: protons, neutrons, and electrons.
- Protons: Positively charged particles found in the nucleus of the atom. Each aluminum atom has 13 protons (atomic number = 13).
- Neutrons: Neutral particles also found in the nucleus, contributing to the atomic mass. The most common isotope of aluminum has 14 neutrons.
- Electrons: Negatively charged particles that orbit the nucleus in electron shells. A neutral aluminum atom has 13 electrons, balancing the charge from the 13 protons.
