Just so, how do you find the atomic number of calcium?
A quick look in the periodic table will reveal that calcium has an atomic number equal to 20 . Now, in order for an atom to be an atom of calcium, it Must contain 20 protons in its nucleus. Always. The number of neutrons can vary, but the number of protons must always be equal to 20 for a calcium isotope.
Correspondingly, how do you find the atomic number? Now you know that atomic number = number of protons, and mass number = number of protons + number of neutrons. To find the number of neutrons in an element, subtract the atomic number from the mass number. Here are a couple example: A single helium (He) atom has a mass number of 4 and an atomic number of 2.
Then, what has an atomic mass of 41?
