How many neutrons does element's x have if it's atomic number is 52 and it's mass number is 153?
Over [174]
Answer: 101 neutrons

An element's atomic number is the number of protons in its nucleus. X has 52 protons. The mass number is simply the number of protons AND neutrons in the nucleus. Since 52 is given, it's correct to assume that the remainder consists of neutrons. 153-52 will give you the number of neutrons.
