It decays into nitrogen-14 ( 14N ) through beta decay. The half-life of carbon-14 is about 5,730 years, which means that after 5,730 years, half of the original amount of carbon-14 will have decayed into nitrogen-14.

What percentage of carbon-14 remains after 17190 years?

The currently accepted value for the half-life of 14C is 5,730 years. This means that after 5,730 years, only half of the initial 14C will remain; a quarter will remain after 11,460 years; an eighth after 17,190 years; and so on.

What percent of carbon would be left after 5730 years?

So we can conclude that the amount of time needed to have one microgram of Carbon 14 in the preserved plant is between 17190 and 20055 = 17190 + 2865 years .Solutions.Number of years since plant diedAmount of Carbon 14 remaining5730= 1 /times 57305 micrograms11460 = 2 /times 57302 /frac{1}{2} micrograms3 more rows

What happens to carbon-14 in a specimen after 5730 years?

Over time, carbon-14 decays radioactively and turns into nitrogen. Carbon-14 has a half life of 5730 years, meaning that 5730 years after an organism dies, half of its carbon-14 atoms have decayed to nitrogen atoms.

What percentage of carbon-14 remains after one half-life?

1. 5,730 years; The graph shows that 50 percent of the carbon-14 atoms have decayed after 5,730 years, so 5,730 is the half-life of carbon-14.

How long will it take in years for 10 grams of carbon-14 to decay to 2.5 grams?

Question: How long will it take for 10. grams of carbon-14 to decay to 2.5 grams? (carbon-14 half life = 5730 years.)

What happens to the amount of nitrogen-14 as the carbon-14 decays?

When carbon-14 decays, a neutron turns into a proton and it loses an electron to become nitrogen-14. The length of time it will take for half the amount of carbon-14 to decay is known as its half-life.
