Rounded to the nearest whole number, how many protons are in an atom of krypton

Explanation:

Atomic number of krypton is 36 and atomic mass of krypton is 84 g/mol.

As, atomic number of an atom is the sum of total number of protons present in an atom. On the other hand, atomic mass is the sum of total number of both protons and neutrons present in an atom.

Therefore,    atomic mass = no. of protons + no. of neutrons

                                84 = 36 + no. of neutrons

                         no. of neutrons = 84 - 36

                                                   = 48

Therefore, we can conclude that in an atom of krypton there are 36 protons.
