What is the atomic number for copper?

Explanation:
The atomic number of an element is the number of protons found in the nucleus of an atom of that element. For copper, the atomic number is 29, indicating that each atom of copper has 29 protons. This number also defines the element itself and determines its position on the periodic table. Copper is located in group 11 and period 4, and it is a crucial metal used in various applications, including electrical wiring and plumbing due to its excellent conductivity and resistance to corrosion. Understanding the atomic number is fundamental in chemistry as it helps categorize elements, predict their behavior in chemical reactions, and understand their properties.
