Which element has the highest atomic number on Earth?

Uranium has the highest atomic number among the elements listed. In the context of the periodic table, the atomic number of an element corresponds to the number of protons in its nucleus. Uranium has an atomic number of 92, meaning it has 92 protons, which is higher than that of gold (atomic number 79), hydrogen (atomic number 1), and carbon (atomic number 6).

This characteristic makes uranium not only significant in nuclear physics and energy production but also in terms of its natural abundance and geological presence on Earth. It is important to understand the implications of an element's atomic number, such as its chemical properties and its position in the periodic table, which can influence its behavior and applications in various fields.
