Nuclear Physics

What is an Isotope?

• A variant of an element with the same number of protons but a different number of neutrons.
• A variant of an element with the same number of neutrons but a different number of protons.
• A variant of an element with the same number of electrons but a different number of protons.

What elements are radioactive?

• All Elements with Atomic number more than 83

• All elements with atomic number under 83

Why are elements over 83 atomic number radioactive?

• They have too many electrons
• In big atoms with a lot of protons repulsion causes instabilty.

• They are too heavy
