Question

36 kr krypton 83.80 krypton has protons neutrons electrons (unlike previous answers, not all of the numbers will be the same. as a general rule, only elements with relatively small atomic numbers will have the same proton neutron and electron counts)

Explanation:

Step1: Recall atomic number property

The atomic number is equal to the number of protons. For Krypton (Kr), the atomic number is 36, so 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. Since Kr is neutral, the number of electrons is 36.

Step3: Calculate number of neutrons

The atomic mass (83.80) is approximately the sum of protons and neutrons. Rounding the atomic mass to 84, and knowing there are 36 protons, the number of neutrons is $84 - 36=48$.

Answer:

Protons: 36
Neutrons: 48
Electrons: 36
