How many protons are In the nucleus of an atom with an atomic number of 15? 14. How many electrons are in the nucleus of an atom with an atomic number of 20? 2,6 15. How many neutrons are in the nucleus of an atom with an atomic number of 25? (use Periodic Table for mass) / 16. What is the mass number of an atom with 3 protons, 4 neutrons, and 3 electrons? Cl?— 17. How many neutrons are in the nucleus of an atom that has an atomic mass of 36 and an atomic number'of 25? l l 18. The atomic number tells you the number of M in one atom of an element. It also tells you the number of m in a neutral atom of that element. The atomic number gives the “identity" of
an element as well as it's location on the Periodic Table. No two different elements will have the 5m—
atomlc number. ' n e ? .
19. The mass number is used to calculate the number of 9 ‘ \ in one atom of an elemen In order to calculate the number of neutrons you must Subtract the 1* from the l I “22 .
