The potassium-37 isotope (K-37) has the following subatomic particles:
- Protons: 19
- Neutrons: 18
- Electrons: 19
Here’s a brief explanation:
Potassium (K) has an atomic number of 19, which means it has 19 protons in its nucleus. The number of protons determines the element. The isotope potassium-37 has a mass number of 37, which is the sum of protons and neutrons in the nucleus. Therefore, the number of neutrons can be calculated by subtracting the atomic number from the mass number: 37 – 19 = 18 neutrons.
In a neutral atom, the number of electrons is equal to the number of protons. Thus, potassium-37 has 19 electrons.
