The element with atomic number 13 is aluminum (Al). Aluminum is a silvery-white metal that is highly valued for its lightweight and corrosion-resistant properties.
In the periodic table, elements are arranged by their atomic number, which indicates the number of protons in the nucleus of an atom. For aluminum, having an atomic number of 13 means it contains 13 protons and, in a neutral atom, 13 electrons as well.
Aluminum is widely used in various industries, including construction, transportation, and packaging, due to its strength-to-weight ratio and versatility. Its prevalence in everyday products makes it one of the most important metals in modern life.
