Question

36 kr krypton 83.798 # protons __ # electrons # neutrons __

Explanation:

Step1: Recall atomic number property

The atomic number is equal to the number of protons. For krypton (Kr) with atomic number 36, the number of protons is 36.

Step2: Recall neutral - atom electron property

In a neutral atom, the number of electrons is equal to the number of protons. So for krypton, the number of electrons is 36.

Step3: Calculate number of neutrons

The atomic mass of krypton is approximately 83.798. Rounding it to 84. The number of neutrons = atomic mass - number of protons. So, number of neutrons = 84 - 36 = 48.

Answer:

protons: 36

electrons: 36

neutrons: 48
