Kr 84.
Atomic number is 36; therefore, it has 36 protons and 36 electrons. The mass number is 84. we know that
mass number = number of protons + number of neutrons. Since mass number is 84 and number of protons is 36, then 84 - 36 will give the number of neutrons. Check my arithmetic. Look at the periodic table to make sure I copied all of the numbers correctly.
