Excited state of an atom, nucleus, or other system that has a longer lifetime than the ordinary excited states and generally has a shorter lifetime than the ground state. It can be considered a temporary energy trap or a somewhat stable intermediate stage of a system of which the energy may be lost in discrete amounts. The many photochemical reactions of Mercury are a result of the metastable state of mercury atoms, and radiation from metastable oxygen atoms accounts for the characteristic green colour of the aurora borealis and aurora australis.

What information is conveyed by the m in 99mTc?
The "m" in 99mTc indicates that the technetium is in a metastable state. This means that the technetium is in an excited nuclear state that will decay to a more stable state by emitting gamma radiation. Metastable technetium is commonly used in nuclear medicine imaging.
What is dynamic metastable equilibrium?
Dynamic Metastable Equilibrium as it relates to Geomorphology describes a system threshold that changes dramatically through time, in an otherwise steady system. In other words, it is a combination of dynamic equilibrium and metastable equlibrium. An example would be changing sea level as it respositions shorelines these changes typically ocurr over thousands of years.
Why metastable state is more stable then excited state?
because according to energy profile,metastable state is lying lower than excited state.as we know that states of lower energies are more stable than states of higher energy.so it is more stable than excited state.
In what state of matter is the sun?
gas
Can oxygen be in plasma state?
Yes, oxygen can be in a plasma state at very high temperatures. When exposed to extreme heat or electrical discharges, oxygen gas can ionize and form a plasma. This plasma state is often found in natural phenomena like lightning or in industrial processes such as plasma cutting.
What is the definition of Metastable state in laser?
In lasers, a metastable state is a state in which atoms or molecules are in an excited state with a longer-than-normal lifetime before emitting a photon and returning to a lower energy state. This allows for the accumulation of a population inversion necessary for laser action.
What radioactive decay processes have no transmutation?
Only gamma, it is the process by which a metastable excited nuclear isomer of an isotope relaxes down to the ground state of the same isotope. Some metastable states must undergo multiple gamma decays through less excited metastable states to reach the ground state.

The "m" in 99mTc indicates that the technetium is in a metastable state. This means that the technetium is in an excited nuclear state that will decay to a more stable state by emitting gamma radiation. Metastable technetium is commonly used in nuclear medicine imaging.

What is metastable ion in mass spectroscopy?
A metastable ion in mass spectrometry is an ion that has been excited to a higher energy state but has not yet undergone fragmentation. These ions can exhibit unique fragmentation patterns different from those of ground-state ions, providing additional structural information. Metastable ions are often formed in collision-induced dissociation experiments.
Why metastable state is more stable then excited state?
because according to energy profile,metastable state is lying lower than excited state.as we know that states of lower energies are more stable than states of higher energy.so it is more stable than excited state.
What is metastable zone width?
The metastable zone width is the range of temperatures within which a substance can exist in a metastable state, meaning it is supercooled or supersaturated and undergoing phase transformation. It is important in processes like crystallization and pharmaceutical formulation to control the conditions for desired product properties.
What kind of flip flop has no invalid or unused state?
None, all flip flops have a small probability of entering a metastable invalid state.
In what state of matter is the sun?
gas
Can water stay liquid at subzero temperatures if you had enough pressure?
The sub zero liquid state is an achievable metastable state with an energy level between that of the gas and solid. Subzero water in this metastable state is said to be super-cooled. In the temperature range 0c to -40c the supercooling phenomenon is prevalent. Reference: See the related link below.
How electrons can stay in the metastable state for longer time?
To leave a state and decay to a lower energy state, the electron must lose energy. In metastable states, there are no lower energy state to go to that have strongly allowed transitions (that is simple emission of a photon, diplole transititions) and so the electron must decay by slower, less probable means (like two photon decay, magnetic dipole decay). Hence, it stays in that state for longer.
Why are some isotopes when written out end in m. I am doing some research for a writing project on isotopes and I am confused because I have found there's Barium-127 but there's also Barium-127m?
I think it stands for metastable - Metastable state is an excited state of an atom or other system with a longer lifetime than the other excited states.
