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.
What else can I help you with?
Are all elements periodically change to become new element s?
No. Only radioactive elements, which undergo radioactive decay can change to different elements.
Do radioactive elements emit radiation all the time?
In order for an atom of an element that is not radioactive to become radioactive, the isotope has to change. This can happen as a result of neutron capture. Neutron capture can simply change the isotope of an atom, as when cobalt-59, which is not radioactive, captures a neutron to become cobalt-60, which is radioactive. Neutron capture can also result in immediate radioactive decay of the atom struck, even if it is not radioactive. For example helium-3 can capture a neutron to produce two atoms of hydrogen, one of hydrogen-3 and one of hydrogen-1.
How is the atomic mass changed?
When the number of neutrons changes, the atomic mass will change.
Does changing the number of neutrons affect what type of element it is?
No. You have to change the number of protrons.(Changing the number of neutrons changes the isotope of the element, but it is still the same element. However, changing the number of neutrons will often result in instability, causing a radioactive decay sequence, which often results in a change in element.)
What is a radioactive atoms?
Radioactive atoms are atoms that have unstable nuclei, which can undergo radioactive decay to become more stable. During this process, they emit radiation in the form of alpha particles, beta particles, or gamma rays. This emission of radiation can cause a change in the atom's composition or energy level.
Can one element change into a different element?
Yes, but only if it is radioactive. Radioactive elements change into different elements through radioactive decay.
How do the atomic number change?
The atomic number of an element is FIXED it can not normally be changed. However, if the element's atom is struck by an atomic particle or the element is radioactive then the composition of the atoms nucleus can be altered. Changes to the composition of the nucleus can cause a NEW element to be formed or indeed split the atom into two NEW smaller/lighter atoms.
Can atoms of radioactive element change into atoms of another element by emitting radiation?
Yes
What kind of decay can change one element to another kind of element?
That would be radioactive decay.
What is the name of the time required to change a part of a radioactive element to a stable element?
The name for the time required for half of a radioactive element to decay into a stable element is called the half-life. It is a constant value unique to each radioactive isotope, and it is used to measure the rate of radioactive decay.
Are all elements periodically change to become new element s?
No. Only radioactive elements, which undergo radioactive decay can change to different elements.
Can the atomic number change over time?
No. The atomic number of an element never changes. It is the number of protons and it defines the element. In certain types of radioactive decay, the number of protons can change, but then it is no longer the same (parent) element, but rather is a new (daughter) element.
What is the name of change that is undergone by an atom of an element made radioactive by bombardment with high-energy protons.?
The change undergone by an atom of an element made radioactive by bombardment with high-energy protons is called transmutation. This process can result in the creation of a different element or a different isotope of the same element.
Does the identity of an atom change during radioactive decay.why or why not?
Well, when an atom undergoes radioactive decay, it can change into a different element. This happens because the nucleus of the atom becomes unstable and releases particles or energy to become more stable. So, while the identity of the atom may change, it's all just a part of nature's way of finding balance and harmony in the universe.
What is the change that is undergone by an atom of an element made radioactive by bombardment with high energy protons?
Artificial Transmutation
What are the differences between a radioactive element and one that transmutes?
Same thing. A radioactive element decays into either a different element (alpha, and beta decay), a lower energy state of the same element (gamma-ray emission), or sometimes breaks into 2 or more pieces (nuclear fission).
When an atom undergoes radioactive decay does it become a different element?
That depends on the type of decay, alpha and beta decay change the atom into a different element but gamma decay does not.
