Radioactive.
All atoms of a specific element have the same number of protons in their nucleus, but the number of neutrons in the nucleus may vary these are isotopes of that element.Hydrogen has several possible isotopes, only the first three of these are commonly referred to:hydrogen or protium or hydrogen-1, 1 proton 0 neutrons, stabledeuterium or hydrogen-2, 1 proton 1 neutron, stabletritium or hydrogen-3, 1 proton 2 neutrons, radioactive halflife 12.26 yearshydrogen-4, 1 proton 3 neutrons, radioactive halflife about 139 yoctosecondshydrogen-5, 1 proton 4 neutrons, radioactive halflife about 910 yoctosecondshydrogen-6, 1 proton 5 neutrons, radioactive halflife 290 yoctosecondshydrogen-7, 1 proton 6 neutrons, radioactive halflife 23 yoctosecondsetc.
halflife
Radioactive waste is nearly always a mixture but it is possible to be a pure substance.
Yes
the halflife is 10 days
Radioactive.
many. one example is lead-214 with a halflife of 26.8 minutes.

halflife
Radioactive substances are unstable as a result of the extra neutrons present in the nuclei of the substance. Non-radioactive substances are stable.
no, halflife is a constant for each isotope's decay process.

The basic idea is to compare the abundance of a naturally occurring radioactive isotope within a material to the abundance of its decay products; it is known how fast the radioactive isotope decays.

A radioactive substance emit nuclear radiations.
Yes
