Answer: (C)

Verified step by step guidance

1. Recall that the number of protons in an atom defines the atomic number of an element, which uniquely identifies the element on the periodic table.
2. Identify the atomic number given in the problem, which is 29 protons.
3. Use the periodic table to find the element with atomic number 29.
4. Check the options provided and match the atomic number 29 to the correct element symbol and name.
5. Confirm that the element with 29 protons is Copper (Cu), as atomic number 29 corresponds to Copper.
