Emissin of light from an atom occurs when an electron what?
Lots of wrong answers out there, tested this on school, the answer is: Drops from a higher to a lower energy level
What is the energy change that occurs when an atom gains electrons called?
The energy change that occurs when an atom gains electrons is called the
What is the difference between the ground state of an atom and excited state of an atom?
An atom is in its ground state when all the electrons in the atom occupy orbitals that result in the minimum chemical potential energy for the atom as a whole. An excited atom is one that stores (at least for a brief interval) additional chemical potential energy as a result of at least one of the electrons in it occupying an orbital with higher energy than the orbital(s) the electrons in the same atom would occupy in the ground state of the atom.
What is energy released on adding an electron to an isolated gas phase atom?
All electron shells represent an energy level - it doesn't matter if its the outermost shell or not. In order for there to be a release of energy the electron has to be coming from a higher energy state. The only energy state higher than the outer-most electron shell would be a free electron. The only way an electron becomes a free electron is that sufficient was provided to lift it from what-ever electron shell (energy level) it was previously in to escape velocity. The energy that it then releases in returning is then this exact same amount of energy.
What is the difference between excited hydrogen atom and any other atom?
Hydrogen atom = 1 proton 1 electron Hydrogen's 1 electron occupies the lowest energy level, 1s orbital. The atom is therefore in its "ground state". When a photon of correct frequency "collides" with a electron in hydrogen's 1s orbital the energy contained in the photon is transferred to the electron. The electron then gets added energy, so it is at a higher energy state. When it reaches this higher energy state the electron jumps to the next energy level and there it starts its new orbit. Hydrogen atom is now "excited" For any other atoms it is the same thing because all atoms can undergo excitation. The only difference between hydrogen's 1 electron and other atom's many electrons is WHICH ELECTRON will be "excited"

The energy change that occurs when an atom gains electrons is called the
What energy is required to remove an electron from an atom?
The energy needed to remove an electron from an atom (in the gaseous state) is called the IONIZATION ENERGY.
What change occurs with the atom when it is emitting light?
An electron has dropped from a higher energy state to a lower one. The photon emitted has precisely the same energy as was lost by the electron.
What does the atom do when an electron in an atom goes from a higher energy state to a lower energy state?
The atom changes size, E= -ahc/r.
What state is an atom in which an electron has moved to a higher energy level?
An atom in which an electron has moved up to a higher level is in an excited state. The lowest state of the atom is called the ground state.Ê
How does an electron position in an atom affect the energy it contains?
If there is an extra electron in the valence level then the electron is in the excited state and is carrying more energy. If the atom is normal then it is in the ground stte and contains low energy.
What is the difference between the ground state of an atom and excited state of an atom?
An atom is in its ground state when all the electrons in the atom occupy orbitals that result in the minimum chemical potential energy for the atom as a whole. An excited atom is one that stores (at least for a brief interval) additional chemical potential energy as a result of at least one of the electrons in it occupying an orbital with higher energy than the orbital(s) the electrons in the same atom would occupy in the ground state of the atom.
How do you generate light?
Light is generated when photons are emitted from an atom. This occurs when an electron on one energy level of an atom falls to a lower energy level.
What is a ground state?
the lowest energy level occupied by an electron when an atom is in its most stable energy state
When does an electron go from the ground state to an excited state?
When the atom absorbs energy of the proper frequency/energy.
