Question

incorrect. what given information can be used to find the atomic number, or number of p (d) potassium - 39 (³⁹k) protons neutrons electrons

Explanation:

Step1: Recall atomic number property

The atomic number of an element is equal to the number of protons. For potassium (K), the atomic number is 19. So the number of protons is 19.

Step2: Calculate number of neutrons

The mass - number is 39. The mass - number = number of protons+number of neutrons. So number of neutrons = mass - number - number of protons = 39 - 19=20.

Step3: Determine number of electrons

In a neutral atom, the number of electrons is equal to the number of protons. So the number of electrons is 19.

Answer:

Protons: 19
Neutrons: 20
Electrons: 19
