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.

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
What is a gas consisting of positively and negatively charged particles?
That is called a plasma. A plasma is usually considered a separate state of matter, i.e., you might say that it is no longer a gas.That is called a plasma.

Name the atoms or elements which exist in metastable state?
Carbon is one of the elements which exist in meta stable state. Diamond is the meta stable state of carbon, which upon given certain activation energy, changes into graphene.
What is the gaslike mixture of positively and negatively charged particles?
That is called a plasma. It only exists at high temperatures in the thousands of degrees, otherwise the positively and negatively charged particles will combine to form electrically neutral compounds of some sort.
What is the definition of Metastable state in laser?
Metastable state in laser is the intermediate state between the e2 and e1 where the excited electron can stay for a comparably long time.
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.

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 kind of flip flop has no invalid or unused state?
None, all flip flops have a small probability of entering a metastable invalid state.
What is the difference between plasma the state of matter and plasma tv?
There is no difference the only thing is plasma is in a TV in plasma screen TV and plasma is outside of the TV in the state or matter.
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.
What is the state of matter when electrons are stripped away from the nuclei?
This is plasma.
In what state of matter is the sun?
gas
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.
What state does lightning have?
state of matter? plasma.
What state is fire?
fire is the state of plasma
