Unstable atomic nuclei decay over time into stable nuclei causing a mineral to be?
radioactive
What is the meaninq of two isotopes stable and unstable isotopes?
Isotopes are atoms of the same element with different numbers of neutrons. Stable isotopes have a balanced number of protons and neutrons, meaning their nuclei do not decay over time. Unstable isotopes, also known as radioactive isotopes, have an imbalance of protons and neutrons, causing their nuclei to decay and emit radiation over time.
What term indicates the process in which unstable nuclide release radiation?
If it is related to Nuclear studies, then the answer would be fusion.
What is the difference between a stable isotope and a unstable isotope?
A stable isotope does not decay and therefore, maintains a constant concentration on Earth. An unstable isotope, also known as a radioactive isotope, decays at a predictable and measurable rate on Earth. An unstable isotope may decay by the ejection of an electron or positron, known as beta decay, or by the ejection of two protons and two neutrons, known as alpha decay.
Is it true that a unstable nuclei will undergo radioactive decay in order to gain stability?
It is true that unstable nuclei will undergo radioactive decay in order to gain stability. These include nuclei of #43 Technitium (Tc), any nucleus containing more that 83 protons and any nucleus with a high neutron-to-proton ratio, such as carbon-14. The most common forms of decay are by emission of an alpha particle (2 protons and 2 neutrons ... a helium nucleus!) or a beta-negative decay in which a neutron bcomes a proton by emitting an electron and an antineutrino.
Process by which unstable nuclei lose energy?
Radioactive decay
Unstable atomic nuclei decay over time into stable nuclei causing a mineral to be?
radioactive
Radioactivity is caused due to what?
spontaneous decay of unstable atomic nuclei.
Why is decay necessary?
Those elements undergo the 'decay' process which have unstable nuclei so decay is necessary to gain the stability. such elements form the smaller stable nuclei as Lead nucleus.
What is a nucleus that is unstable and undergoes decay?
Atomic nuclei that are unstable and decaying are said to be radioactive. Radioactive decay involves alpha, beta and gamma particle emissions.
What is the spontaneous process through which unstable nuclei emit radiation?
Radioactive decay or radioactivity
The unstable nuclei isotope cobalt -60 will decay to Nickel -60 by emitting what?
beta+
Will unstable nuclei all undergo radioactive decay in order to gain stability?
Yes
What term indicates the process in which unstable nuclei releases radiation?
The term is "radioactive decay".
What is the process in which the atomic nuclei of unstable isotopes release fast moving particles and energy?
radioactive decay or simply decay.
Radioactive decay occurs when atoms of an unstable element?
It means that massive nuclei break apart.
What is the meaninq of two isotopes stable and unstable isotopes?
Isotopes are atoms of the same element with different numbers of neutrons. Stable isotopes have a balanced number of protons and neutrons, meaning their nuclei do not decay over time. Unstable isotopes, also known as radioactive isotopes, have an imbalance of protons and neutrons, causing their nuclei to decay and emit radiation over time.
