How long would it take a radioactive element with a mass of 20 grams to decrease to 5 grams if the half life is 1000 years?

You would have to wait 2,000 years for this to occur.
Half of 2,000 is 1,000.
Half of 1,000 is 500.
This process happens twice. 1,000 years * 2 processes = 2,000 years.

Would you use grams or kilograms to measure a cell phone?
grams
How would you measure a mouse in grams or kilograms?
I would describe their weight in grams.
Does a pen weigh 10 grams or 100 grams?
A pen would weigh approximately 10 grams. 100 grams would be about 100 grams of feathers.
What would happen to the number of number of bears if the salmon were to decrease?
the bears would decrease because bears eat salmon
A 50 computer program is on sale for 37.50 what is the percents decrease?
It would be a 25% decrease.
A radioactive element has a half-life of 3000 years. If a sample of this element begins with a mass of 60 grams how long would you have to wait for the mass to decrease to 15 grams?
You would have to wait 6,000 years for this to occur, because it requires twice the half-life to reduce the radioactive isotope to 1/4 of its original mass.

What kind of decay can change one element to another kind of element?
That would be radioactive decay.
If you had a stable element 115 could you then have an isotope of it that would be non-radioactive?
If you had a stable element 115, then by definition there would need to be at least one non-radioactive isotope. Stable elements are those that have at least one nonradioactive isotope. Of course, the other isotopes of the element could all be radioactive.
What is am element?
Element Am is Americium. Americium is radioactive element number ninety five. I would not wanna mess with Americium
Im doin a project on a radioactive element with a partner-he's kinda reckless.Im worreid he actually bring that radioactive element into my house to work with.I don't want radiation poisoning.Will he?
Really? Are you that stupid? Who in the right mind would get a radioactive element or even find the place to buy one? You sir are an idiot...
What would happen to an atom if the number of protons in the nucleus changed?
It would become a different element. It could become radioactive.
How can nuclear radiation be absorbed?
Yes. Any element which is radioactive may bond together with other molecules and atoms, just as much as any other non-radioactive element. However, radioactive elements would have a slightly greater pull towards their bonded species if their nucleus has more neutrons than what is normal for non-radioactive elements.
Why are protons and neutrons always equal in number?
Because they are both in the nucleus and if they weren't the element would be radioactive.
What would happen if we combined every radioactive element and made a nucleur bomb?
That is not how nuclear bombs are made.
What is the half-life of every radioactive element?
The same element can have different half-lives, for different isotopes. You can find a list at the Wikipedia article "List of radioactive isotopes by half-life". This list is NOT complete; a complete list would have about 3000 nuclides (that is, isotopes).
What is the term for the element that a radioactive isotope decay into?
The atom that results from nuclear decay is called the daughter atom. The element of the daughter atom would be called the daughter element. The atom that decayed is called the parent.
