HELP! The atomic number of krypton (Kr) is 36, and its mass number is 84. How many neutrons does it have?
timurjin [86]

Answer:

C. 48

Explanation:

Simple thing to bear in mind; The number of neutrons is equal to the Atomic number - the Mass number. Because the Atomic number tells you the number of Protons, whilst the mass number tells you the number of both PROTONS and NEUTRONS. So 84 - 36 is 48. You have 48 neutrons
