fluoride
which element present in our toothpaste protects out tooth from the tooth decay?
Fluoride
Fluoride helps prevent tooth decay
Fluoride.
this depends on what type of decay you are asking about. the decay of tissue, or the decay of elements. elemental decay is the process in which an element (carbon, hydrogen, uranium, etc...) loses atoms, and is unpreventable. the decay of tissue is a process where decomposers such as scavengers (vultures), and bacteria eat away at the once, living matter. the only way to prevent this is to keep the composers away from the "thing."
The lightest "element" that can undergo radioactive decay is the isotope hydrogen-3, which undergoes beta decay. The lightest element with no radioactively stable isotopes is technetium, and its isotopes have different modes of decay.
The half-life has a specific value for each isotope.
That would be radioactive decay.
That depends on the type of decay, alpha and beta decay change the atom into a different element but gamma decay does not.
Actinium-227 decay to francium-223.
It turns into another element.
