Carbon dating only applies to artifacts or objects containing carbon atoms (C14). If the entirely metal artifact does not have carbon atoms then carbon dating is not useful. But if the artifact is made of wood or something like that, then it will be useful. Wood contains carbon atoms including carbon
Why has so much technology been developed during the past years?
To a large measure, it is because of important advances in our understanding of the stucture of matter. Nuclear reactions change the composition of an atoms. All nuclei with atomic numbers greater than 83 are. Why is carbon dating not useful for artifacts made of entirely metal.
Carbon dating only applies to artifacts or objects containing carbon atoms. Compare the penetrating power of alpha, beta, and gamma radiation. Alpha-weakest Beta- medium Gamma-strongest.
Why do nuclei need neutrons to be stable? Like charges repel each other,neutrons serve better as. Buffer so that the protons don't push each other apart. Describe two nuclear reactions. H bombs a bombs.

The physicist Henri becquerel discovered radioactivity while working with a sample of. Rutherfords alpha scattering experiment showed that the charge on the nucleus of the atom must be.
In his experiments with cathode ray tubes, Thompson concluded that cathode rays were composed of particles that were. Matter is neither created nor destroyed in any process. A given compound always has the see more relative numbers and kinds of atoms.

All atoms of a given element are identical, but they differ from those of any other element. A given compound always contains the same elements in the same proportions by mass. Each element is composed of extremely small particles called atoms. All matter is composed of tiny, invisible parts. Atoms are neither created nor destroy per in chemical reactions.
The largest particle of an element that retains the chemical identity of that element. The amount of time it takes for half of a substance to decay.
What is the purpose of the discussion concerning cutting aluminum foil into smaller and smaller pieces? To show us that things can get smaller and smaller "ad infinitum". What did democritus believe about matter back in bce. All matter that makes up the world all around us is actually composed of tiny, invisible particles. He called these atomos. The smallest part of an element that retains the chemical identity of that element. Why were the ideas of Democritus not accepted?
He couldn't answer the questions about atoms. Why we're the ideas of Democritus read more in the 17th and 18th centuries? This is when scientists stopped relying on logic, but also on observations and experiments. Why is there such a diversity in nature if there are only about different kinds of atoms.
The atoms combine to make several different substances. Are we able to see atoms?

Describe how Henri becquerel came to realize that uranium atoms spontaneously give off strange particles? He placed a uranium sample on some unexposed photographic film, and then an image appeared on the screen caused by unknown radiation. Name two other scientists who discovered radioactivity. Marie and Pierre curie radium and polonium.
List the three types of radioactive particle. John Dalton's atomic theory which built on the work of laoviser and proust. Henry becquerel- radioactivity JJ Thompson- electron, plum pudding.
