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.

Where do the electrons of a atom stay?
Inside orbitals in the electron cloud
What causes bonds to stay together?
Bonds stay together by electrons that travel on the atoms combined, holding the atoms together.
Do protons travel through an electric circuit at or near the speed of light?
Electricity, this may be electrons in a direct current. In an alternating current the electrons stay where they are and it is only the energy that moves between electrons.
Will opened soda stay carbonated longer if it is stored in the fridge?
probably not
Why metals are known to exhibit a high electrical conductivity?
Metals have high electrical conductivity because of their "sea of non-localized electrons". In metallic bonding, the valence electrons of a particular metallic atom do not have to stay with that atom, they are not fixed in one place, they flit around in the metal taking the place of other electrons that have strayed.In metals, the valence shell is exactly half full. When large numbers of atoms of the same metallic type are neighbors, all of the electrons in the valence shells are at nearly the exact same energy state as "free" electrons as well as of those around neighboring atoms. Little force is required to move large quantities of electrons in the same direction, and little heat is generated.In covalent bonding some valence shell is not exactly half full. Atoms tend to bond with complementary molecules whose valence shells will "complete" them. Now the electrons in adjacent atoms have significantly different quantum energy states. The electrons are constrained within a molecular bond and stay put until enough energy arrives to free the electron from that quantum state; the molecule is ionized and changes shape. When the quantum state changes (either freeing or reacquiring an electron), heat is released in the form of "ringing" molecules.
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.
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.

YES
