Protium is the name of a common hydrogen isotope. This isotope has a single proton and does not have any neutrons.
Potassium has three naturally occurring isotopes: potassium-39, potassium-40, and potassium-41. The most common isotope is potassium-39, which makes up about 93% of naturally occurring potassium.
No, the Neutrons vary with the element, in the same group as well, it depends on the isotope, like lithium for example, the most commonly occurring isotope has 4 neutrons, whereas sodium has 12
The most common isotope of selenium is selenium-80, which makes up about 50% of naturally occurring selenium.
The most common plutonium isotope is plutonium 239.
