700 million years
By definition, 50%. Half life is the time for half of the original sample to decay.
Uranium has a high half-life, so it changes very quickly.
The half-life is 4 days. That means half of it will be gone in 4 days, and that leaves half of the original sample. In another 4 days, half of the remaining half will have decayed. And that will leave only 1/4 th of the original sample. That means 3/4 ths of the original sample will have decayed. In 8 days, three fourths of a sample of a radioactive element with a half-life of 4 days will have decayed.
The most important isotope - Es-253, has a half life of 20,47 days.The longest half life is for the isotope Es-252: 471,7 days.But einsteinium has 19 isotopes and 3 isomers, each with a different half life.
The half life of plutonium-239 is 2,41.10e+4 years.
700 milliion years. The definition of half-life is the period of time during which one-half of the atoms of an element undergo decay into other elements.
can cause lung cancer
The reaction produces more neutrons than were needed to start it.
No. Half Life: Opposing Force does not require neither Half Life nor Half Life: Blue Shift.
Nuclear energy as used in power plants results from fission of uranium235 and plutonium239
The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.
No, only Half-Life and Half-Life: Decay.
Antibiotics do not have a half life.
You say 'I've missed Half my life' which is short for : "I have missed half my life'
The term is called half-life. It is the time it takes for half of the radioactive nuclei in a sample to decay.
Buy Half Life: Source Or Buy Garrysmod a Half-Life 2 Modification and get the addon "Half-Life Rennaisance" Link to Half Life Rennaisance: http://www.garrysmod.org/downloads/?a=view&id=57033 Enjoy!
No. Half-Life: Source runs on the Source engine. The original Half-Life doesn't. You cannot use mods made for the original Half-Life on Half-Life: Source because they run on different engines and it won't work.
