Question

The half-lives of unstable isotopes vary from milliseconds to billions of years

True or false

Answer 1

True

Step-by-step explanation:

Answer 2

True

Step-by-step explanation:

The half lives of unstable isotopes of elements vary from miliseconds to billions of years, for example Bismuth-209 has the longest half life known by the human and the scientists and it has still billions of years to this day, and there are elements that cannot withstand seconds before decaying into another element, so the statement is True.
