Question

how many protons are in a neutral atom of radon (rn)? how many electrons?
number of protons =
number of electrons =

Explanation:

Step1: Recall atomic number of radon

The atomic number of radon (Rn) is 86. The number of protons in an atom is equal to its atomic number. So, number of protons = 86.

Step2: Recall charge of neutral atom

In a neutral atom, the number of electrons is equal to the number of protons. So, number of electrons = number of protons = 86.

Answer:

Number of protons = 86
Number of electrons = 86
