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.
In which state does the electron possess more energy?
An electron possesses more energy in the excited state than the ground state.
In matters lowest energy state does it tend to be more stable?
Yes, in general, the lowest energy state of a system tends to be more stable because it represents a state where the system has achieved a balanced and minimally energetic configuration. Systems naturally tend to move towards their lowest energy state to increase stability and minimize energy.
Is bromine more stable as gas or liquid?
Bromine is more stable in its liquid state at room temperature and pressure. In its gaseous state, bromine is highly reactive and can readily undergo reactions.

Why triplet state is found to be more stable than excited state?
Why triplet excited state is found to be more stable than singlet excited state?
Do atoms in the excited state have more electrons than in the ground state?
Yes, because an atom in an excited state will normally give off energy and go to a less-excited state or to its ground state. Some atoms have long-lived excited states and are called "metastable".
What characterized a radioactive atom?
Its nucleus is unstable.
What is HTE difference between an atom in the ground state and an atom in an excited state?
Atom in the ground state is stable but atom in excited state is not stable the main reason for this is their energies.Atoms in excited state has more energy so they undergo chemical reaction so they are not stable but atoms in ground state has less energy than the excited state so they dont undergo chemical reaction.

What is the electron configuration of copper at excited state?
The electron configuration of copper at an excited state is [Ar] 3d104s1. In the excited state, one of the 4s electrons is promoted to the 3d orbital to achieve a half-filled d orbital, which is a more stable configuration.
In which state does the electron possess more energy?
An electron possesses more energy in the excited state than the ground state.
An atom in an excited state contains more of what type of energy than the same atom in the ground state?
more electrons than an atom in the ground state
Does a hydrogen atom expand or contract as it moves from its ground state to an excited state?
A hydrogen atom expands as it moves from its ground state to an excited state. This is because the electron in the excited state is farther away from the nucleus, increasing the average distance between the electron and proton in the atom.
A state in which an atom has more energy than it does at its ground state?
An atom is in an excited state when it has absorbed energy, causing its electrons to move to higher energy levels. These excited electrons are unstable and eventually return to their ground state by emitting energy in the form of light or heat.
What limit is placed on electrons in the Bohr model in the atom?
A shifting electron will always move from a more excited to a less excited state.
