Copper has natural isotopes of 63,67. And other isotopes are known at least from 58 through 70. But these are unstable.
Isotopes are used to create energy in at least two ways: # The isotopes are allowed to heat water into steam, and the steam turns a generator. # The isotopes are allowed to heat one end of a "thermopile", and the thermopile powers electronics. (This is how the deep space probes get their power.)
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.
Radon is a noble gas and is radioactive. All of the other noble gasses have at least some synthetic radioactive isotopes. Radioactive isotopes of both krypton and argon exist in nature in trace quantities.

One cent coin, which is used as least valued coin. Example: he had a lot of pennies with him.

No way to answer, because there are at least 2 common types of US pennies. There are approximately 145 copper pennies in a pound.There are approximately 181 copper plated zinc pennies in a pound.
no. it is a solid isotope and is the least harmful of the plutonium isotopes.
At least one for each knife.

Not all of the transition elements are radioactive. Many of them are, and some of them have common radioactive isotopes, but some of them have no naturally occurring radioactive isotopes. Please note that all elements have synthetic radioactive isotopes, at least.
no they get cleaner with vineger at least that's what I know
If pounds represent British pounds, then since Britain has gone metric (at least in coinage) 16.05 pounds equals 1605 pennies
Because a penny saved is a penny earned. i dont agree at least u could of back it up with more info then i just used it caused i needed this for a project
It will greatly depend on the size of the cup. The weight of the pennies will have to counter act the bouyancy of the cup. It will probably take at least 60 - 100 pennies.
