Which element has atomic number 29?

Explanation:
The number of protons in an atom’s nucleus, called the atomic number, identifies which element it is. Copper has an atomic number of 29, meaning it has 29 protons. That makes it the element associated with 29. The other elements listed have different numbers of protons: iron has 26, nickel has 28, and zinc has 30. So atomic number 29 corresponds to copper (Cu).
