Most elements - metals and non-metals - have both stable and radioactivie isotopes. If an element is a type of atom, an isotope is something like a "sub-type". Two isotopes of the same element have the same number of protons, but a different number of neutrons.

Oh, dude, let me break it down for you. So, the three families that contain no radioactive elements are the noble gases, the alkaline earth metals, and the alkali metals. It's like they're the cool kids who don't mess around with that radioactive drama. Just chillin' with their stable atomic structures, you know?
The groups from 3 to 12 are called transitional metals because the last two shells of the elements included in these groups are incompletely filled. They are also included in d-block.Groups 3 through 12 are called the transition metals or the d-block.
They are metals.
One type of element is the metals (located on the left side of the periodic table, s-block): Li, Na, Mg, Ca, Fr A second type is the transition metals(located in the center of the periodic table, d-block): Cr, Mn, Y, Sc, Cu A third type is non-metals(located on the right side of the periodic table, p-block): P, Si, N2, C, O2 I hope this is what you referring to when you said "types".
Lithium and sodium are alkaline metals that have 3 occupied energy levels.
Three families of elements that contain no radioactive isotopes are the noble gases (such as helium, neon, and argon), the alkali metals (such as lithium, sodium, and potassium), and the alkaline earth metals (such as beryllium, magnesium, and calcium). These families consist of stable elements that do not have any naturally occurring radioactive isotopes.

Dental Caries is the scientific name for 'tooth decay.'

After 3 replication cycles, 87.5% of the DNA will be radioactive. Each cycle doubles the amount of DNA, so after the first cycle, 50% will be radioactive, after the second cycle, 75% will be radioactive, and after the third cycle, 87.5% will be radioactive.
