It really applies to radioactive isotopes, not elements. An element may have different isotopes, some of which are radioactive, some not.
The half-life is the time it takes for half of a sample to decay - for the atoms to convert to some other type of atom.
none, uranium itself is unstable, there are no stable elements after bismuth; and even some researchers suggest that bismuth is an unstable radioactive element with a halflife approaching twice the age of the universe.
No, halflife is a bulk statistical property of a quantity of an isotope of an element.Individual nuclei do not have halflives, instead they have a probability of decaying at the current moment of time.
The length of time required for half of a sample of radioactive material to decay
many. one example is lead-214 with a halflife of 26.8 minutes.

no, halflife is a constant for each isotope's decay process.
Hydrogen has three isotopes: protium (1H), deuterium (2H), and tritium (3H). Protium is the most abundant and consists of one proton and one electron. Deuterium contains one proton, one neutron, and one electron. Tritium has one proton, two neutrons, and one electron.
A radioactive element is one that discharges radiation. Uranium is a radioactive element. A radioactive element is very dangerous if you don't have protective clothing. You should never go near a radioactive element.
A radioactive element is characterized by having unstable atomic nuclei that decay and emit radiation in the form of alpha particles, beta particles, or gamma rays. This decay process results in the transformation of the element into a different element or isotope.
