How old in years is a fossil sample that has 12.5 percent C-14?
The half-life of Carbon-14 is 5,730 years. As such for the carbon-14 to decay from 100% to 12.5% it would take three times the half-life of the material.100% (1st half life decay period) 50% (2nd half life decay period) 25% (3rd half life decay period) 12.5%.Therefore = 5730 x 3 = 17,190 years.
What period does thorium belong in?
Thorium is a member of the actinoids family, period 7 in the periodic table of Mendeleev. The half life of 232Th is 1,405.1010 years.
What is the half life of promethium?

Is a period of an element the amount of time it takes for half of a radioactive isotope to decay?
False- the period is the horizontal row the element is in
How can the element Americium change into the element neptunium?
Americium decays into neptunium-239 through alpha decay. It has a half-life of 7,370 years.
What is the half-life of neptunium-238?

Why is it useful to create neptunium by bombardind uranium with protons even though neptunium disintegrates in about two days?
The bombardment of uranium is with neutrons not protons.Neptunium has many isotopes; for example 237Np has a half life of 2,14.106 years.237Np will be used by United States as nuclear weapon.Other possible applications: precursor for the preparation of plutonium isotopes Pu-236 and Pu-238, isotopic tracer, in neutrons detectors.

Where in life do you encounter neptunium?
You have any chance to encounter neptunium.
When neptunium is combined with another element what new compound can it make?
Neptunium is a metal, and therefore it can in theory form all the usual kinds of compounds that metals form; it could combine with oxygen and form neptunium oxide. However, neptunium is a radioactive element with a very short half-life, therefore it does not stick around long enough to engage in chemical reactions, or even if it did, the resulting compound would also exist only for a very brief period of time.
What is neptunium used for in everyday lives?
Neptunium has not today any use in every day life.
What is the half life of the radioactive isotope?
The half life is the period of time it takes radioactive decay to transmute one half of the isotope present at the start of the period to a different isotope, usually an isotope of a different element. This period of time is different for different isotopes, with known isotope half lives ranging from femtoseconds to many billions of years.
