The number of subatomic particles inside and outside the nucleus of the krypton atom is as follows: inside nucleus= 84 outside nucleus= 36.

SUBATOMIC PARTICLES:There are three subatomic particles in the atom of an element. These three subatomic particles: proton, electron and neutron. The atomic number is the number of protons in the atom. In a neutral atom, the number of protons and electrons are the same. Hence, the number of protons and electrons in krypton atom is 36. The number of neutrons of an atom can be calculated by subtracting the number of protons from the mass number. The number of neutrons in krypton atom is (84 - 36) = 48.Therefore, the number of subatomic particles inside and outside the nucleus of the krypton atom is as follows: inside nucleus = 84 outside nucleus = 36.

Answer from: Manuel2019

inside nucleus= 84 outside nucleus= 36

Explanation:

Recall that an atom is made up of three subatomic particles named protons, neutrons and electrons. The proton and neutrons are found inside the nucleus while electrons are found outside the atom nucleus.

So, given that:

Atomic number of krypton = 36

Mass number of krypton = 84

The number of protons = 36 (same as atomic number)

The number of neutrons = (Mass number - Number of protons) 84 - 36 = 48

Thus, particles inside nucleus = (protons + neutrons) = 84

While particles (electrons) outside nucleus = 36 (same as the atomic number which is 36).
