The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.
The term is called half-life. It is the time it takes for half of the radioactive nuclei in a sample to decay.
Pu-239 has a half-life of about 24,100 years.
The time it takes for half of a radioactive sample to decay is known as the half-life. Each radioactive element has a unique half-life, which could range from fractions of a second to billions of years. The half-life remains constant regardless of the size of the initial sample.
Some examples of radioisotopes and their half-lives are: Uranium-238: Half-life of 4.5 billion years Carbon-14: Half-life of 5,730 years Technetium-99m: Half-life of 6 hours Iodine-131: Half-life of 8 days

Boron-11 is the most abundant isotope of boron in nature because it is a stable isotope with a relatively long half-life, making it less likely to decay into other isotopes. Boron-10, another naturally occurring isotope, is less abundant because it is less stable and undergoes neutron capture to form boron-11.
boron helps makes magnets but plants need boron for proper health and we need plants.

Pure boron (a metalloid) is not found in nature. Boron will be combined with something else. Pure boron could be shiny, but will usually be a brown powder when combined with carbon.
Ah, freezing points are like little friends in the world of chemistry, aren't they? Boron, with its gentle nature, freezes at a temperature of 2076 degrees Celsius or 3769 degrees Fahrenheit. Just imagine it transforming into a beautiful, solid state, like a peaceful snowflake drifting down from the sky.
There are 5 neutron in b-10, and 6 in boron-11
No. Half Life: Opposing Force does not require neither Half Life nor Half Life: Blue Shift.
boron was named boron because of the properties it has
There are no stable isotopes with atomic mass 8. A boron ion could reasonably have charge +3, but 8B is very radioactive with a half life of less than a second.
Boron discovery is the discovery of Boron.
No, only Half-Life and Half-Life: Decay.
