Identify the element symbol given in the problem, which is Ca.
Recall that the atomic number of an element corresponds to the number of protons in its nucleus and is unique to each element.
Use the periodic table to find the element with the symbol Ca, which stands for Calcium.
Locate Calcium on the periodic table and note its atomic number, which is the number usually found above the element symbol.
Confirm that the atomic number of Calcium (Ca) is 20, meaning it has 20 protons.
