The atomic mass number of Krypton is 83.80 or 84 and the atomic number is 36, so, 84-36=48.
How do we find atomic mass?
Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
What does the 84 mean in krypton 84?
The bottom number tells you how many protons you have in the nucleus of this element. In the case of Krypton-84, this means that you have 84 nucleons, where 36 of these are protons, and the remaining 48 are neutrons.

What is krypton on the periodic table?
krypton (Kr), chemical element, a rare gas of Group 18 (noble gases) of the periodic table, which forms relatively few chemical compounds. About three times heavier than air, krypton is colourless, odourless, tasteless, and monatomic.
What is in atomic mass?
Atomic mass indicates the size of an atom. Although technically the mass is the sum of the mass of all the protons, neutrons, and electrons in an atom, the mass of an electron is so much less than that of the other particles, that the mass is simply that of the nucleus (protons and neutrons).
Where is the mass number?
An element’s mass number is unique to that element, and it’s listed right underneath the element’s symbol in the periodic table. The mass number of an element is not the same as its atomic number.
Is mass number and atomic mass same?
The mass number is the sum of the number of protons and neutrons in an atom. It is a whole number. The atomic mass is the average number of protons and neutrons for all natural isotopes of an element. It is a decimal number.
