What happens for an atomic emission of photons to occur?
Electrons fall from higher energy state to lower energy state in atoms. This can be from outer shells to empty spaces in inner shells or from outside the atom to an empty space in a shell.
What are valence electrons and shells?
Valence electrons are the ones which participate in chemical reactions in some way, either by moving from one atom to another, or by being shared with another atom. They are found in the outer shell of an atom (there are usually inner shells with other electrons that are not valence electrons, although in the lightest elements, there are no inner shells and all electrons are valence electrons).
How come it is that outer shell electrons participate in bonding and not the electrons that in other shells?
Inner shells of electrons are always full and cannot accept any additional electrons. Also, they can not generally lose electrons because the energy require to remove an electron from an inner shell is generally too high to be achieved in a chemical reaction.
How do the outer electrons in metal atoms differ from the outer electrons in nonmetal atoms?
Those electrons are called the valence electrons. They are the ones that can be transferred and form bonds with other atoms.
Are electron shells and electron dots the same thing?
no. electron shells are just what contain the electrons. the inner most shell contains 2, then 8 and so on.
How are the inner shell electrons represent in a Lewis structure?
In a Lewis dot structure (also called an electron dot structure) there are no inner electrons and shells shown because Lewis dot structures are usually used to show bonds between elements, and the inner electrons are never usually involved with the bonding of atoms.

How many electrons can be held in the innermost energy level of atoms?
Use the figure 2n2 where n = the shell number. There are many levels of shells, so "inner" is not a very specific term. If you mean "inner-most" shell however, then the answer would be two, since n = 1.

Do Electrons from inner shells link up to form compounds?
No, only outer shell electrons participate in chemical bonds.
What element contains 7 electrons and 7 protons?
You should understand that while neutral atoms have the same number of protons and electrons, they do not usually have the same number of protons and valance electrons, because except for hydrogen and helium, atoms also have electrons in the inner shells, which are not valance electrons. Therefore, there is no atom which has 7 protons and 7 valance electrons, although there is an element that has 7 protons, and there are several elements that have 7 valence electrons.

How many shells does oxygen have?
2
Does an electron in the third shell has more energy than in the first shell?
when electons are more closer to nucelus it has less energy. when they are away from nucleus they are more energetic. how far electons will be away from nucleus, more they can influence other atoms
