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 definition of excited state electron?
An atom will go into an excited state when the electrons are given extra energy. Then after the electrons have been excited it will eventually go back to ground state producing a light as it returns to its normal 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".
Why are cuprous ions less stable than cupric ions?
due to its oxidation states or simply the explanation is in the ground and excited states of an atom
Do atoms in excited states emit radiation randomly at any wavelength?
yes
What are ground and excited states?
In an atom, the electron or electrons have a certain normal distance from the atomic nucleus, and when they are at the normal distance, that is described as the ground state. If energy is added to an electron it will move further from the nucleus, or depending upon the amount of energy, may leave the atom entirely. If it moves further from the nucleus it is in an excited state. If it leaves the atom it is ionized.

What is difference between a ground state electrons configuration and an excited state configuration?
In the ground state all the (only one for Hydrogen)) electrons is in the lowest stable orbit. If the electron gains energy (usually from a photon) it will orbit in a higher energy state (called excited).
What is the electron configuration of aluminum in the excited state?
Indeterminate. There are an infinite number of possible excited states.

A quantum of energy as defined in the Quantum Mechanical Model is a?
It isn't so much a matter of there being a given "quantum of energy" as much as energy is quantized. This means that particles that behave quantum mechanical laws can only have certain values of energy and not the values in between. The most popular example of this is an electron in an atom. Quantum theory tells us that the electron can be in it's ground state energy, which has a given value, or it's first excited state, which has another given value, or any higher excited state. However, you cannot observe an electron with an energy value in between the ground state and first excited state, or between any two consecutive excited states. This is what it means to have quantized energy: only certain discrete values are allowed.

How or where is gamma radiation formed?
In the atomic nucleus as protons and/or neutrons fall from excited states towards their ground state.
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.
How is visible light made?
Light is emitted when an electron drops from the orbit of an excited state, into its natural state. The quantum of light emitted is characteristic of the change in energy of the two electron states, and also of the actual element involved.
Energy gap between the excited and ground states for the sodium ion?
Ephoton=h(Planck's constant) v (frequency of the radiation)
