What is the process by which an element slowly decays over time?

It is through radioactive decay that a quantity of an unstable element will decay over time. A material that is unstable will undergo this process, and the sample is said to be radioactive.


What happened to the part of the plutonium that is no longer ther?

Plutonium is a radioactive element that decays over time, transforming into other elements through a series of radioactive decays. When plutonium decays, it releases energy in the form of radiation and transforms into a different element. This process continues until the plutonium is no longer present.


How does the composition of a rock containing a radioactive element change over time?

The compositionn of a rock containing a radioactive element changes over time by: decaying and changing into another element; the amount of the radio active element goes down, but the amount of the new element goes up.


When an isotope decays over time and becomes a different element what is it called?

It is called radioactive decay. During this process, an unstable isotope loses energy or particles to become a more stable element.


How can atomic numbers be used distinguish one element from another?

they can distinguish one element from another becasue by the protons and the nuetrons , they can over come almost anything.


What do you call a atom that decays?

An atom whose nucleus decays over time is called radioactive. Some examples of radioactive substances are uranium, plutonium, and einsteinium.


How is the element's period related to the number of energy levels over which its electrons are spread?

The element's period indicates the number of energy levels or electron shells that its electrons occupy. Each period corresponds to a new energy level being filled by electrons. Moving from left to right across a period, the number of energy levels increases by one as you go from one element to the next.

What should you do if you got your period on the 22nd and you got your birth control shot on the 26th but you still haven't stopped your period?

i was on my period when i got my shot and it lasted for over 14 days. After it ended i havent had another period for over a year now.


What happens to a radioactive material over time?

It disintegrates into its daughter nuclei that are much more stabler than the radioactive nuclei. If a sample of radioacictive material is left it will decay into another element over a period of time. Note that complete decay is not possible. A fraction of the original radioactive material will always remain in the sample.


Why do bruises turn greenish after a few days?

The heme in the red blood cells decays over time into other compounds, one of which appears slightly greenish. The green compound then decays further into a yellowish compound.
