How long does it take for 200 grams of carbon 14 to decay into 100 grams?
The half-life of carbon-14 is about 5700 years. This means that in 5700 years, half of the original 200 grams (100 grams) will have decayed. To decay from 200 grams to 100 grams, it will take one half-life, or 5700 years.
The half-life of carbon-14 is 5730 years. How long will it take for the number of carbon-14 nuclei in a sample to drop to a quarter of the original number?
It will take two half-lives for the number of carbon-14 nuclei to drop to a quarter of the original number. Since the half-life of carbon-14 is 5730 years, it will take 2 * 5730 years = 11460 years for this to occur.
How many types of subatomic particles are there?
Over 200 types are known.However, there are 3 that form the basic structure of atoms: protons, electrons, and neutrons. There is also an anti-particle of the electron, the positron, that is seen in radioactive decay.
The half-life of F-20 is 11.4 seconds When there are 200 atoms of F-20 in a sample a scientist starts a stopwatch The scientist stops the stopwatch at 34.2 seconds there are atoms of F-20 re?
Atomic decay is a random phenomenon whose distribution is exponential (generally). Thus if the average lifetime is t0 and you wait a time t, the probability that a single atom decay is p=(1-exp(-t/t0)) Thus if you have N atoms, the average number of atoms that decay in the tine t is <N> = N0 (1-exp(-t/t0)) where N0 is the initial number. naturally in a specific experiment the real number of atoms that decay in a time t will not be exactly <N>, this is only the average number over a potentially infinite number of experiments. However, greater N0, more likely the number of atoms observed in a specific experiment will be near to <N>. In your case <N>=188.1 and the expected deviation is of the order of 13, thus the result could fluctuates with high probability between 200 (that is all decay) and 162 (2 sigma point).
What is a fact family that 200 belongs to?
A fact family that 200 belongs to is: 200 + 100 = 300 300 - 100 = 200 200 x 1 = 200 200 / 1 = 200
What is the Product of 20 and 10?
200 is the product
What fraction of the radioactive atoms currently present will be left after four minutes if a sample of gas has a half life of two minutes?
After two minutes, half of the radioactive atoms will remain. After another two minutes, half of the remaining atoms will decay, leaving 1/4 of the original amount. Therefore, 1/4 of the radioactive atoms will be left after four minutes.
