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).
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.
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.
Why are atoms more likely to lose an electron as you go down a group?
this occurs because of the shielding effect of inner electrons.as we go down the group- number of electronic shells increases, which restricts the outer most electrons from being attracted by the protons of nucleus.as the result of this effect the outer most electrons are loosely attracted by the nucleus,resulting the increase of atomic radii.hence making it easier for atoms to lose electrons down the group.
How many inner shell electrons are there in Helium?
Since Helium is a noble gas meaning it is stable, and the fact that it has one shell, it has 2 shells in its inner-most shell.
Why do outer shells of atoms hold more electrons?
The outer shells of atoms can hold more electrons because they have higher energy levels compared to inner shells. These outer shell electrons are farther from the nucleus and experience weaker attraction forces, allowing them to occupy a larger electron capacity.
Where are the core electrons located?
Core electrons are located in the inner electron shells of an atom, closest to the nucleus. These electrons are tightly bound to the nucleus and are not typically involved in chemical reactions or bonding with other atoms.
Do only outer shells gain or lose electrons with other atoms?
Yes. Only the valence shell will interact with other atoms. This is how different elements are different from eachother. The electrons under the valence shell are never touched. Yes.

How many inner shells is sodium?
Sodium has two inner shells. The first inner shell can hold up to 2 electrons, while the second inner shell can hold up to 8 electrons. Sodium's electron configuration is 2-8-1, with one electron in the outermost shell.
What is the effective nuclear charge of an atom primarily affected by?
The effective nuclear charge of an atom is primarily affected by the number of protons in the nucleus and the shielding effect of inner electron shells. As electrons in inner shells shield outer electrons from the full attraction of the nucleus, the effective nuclear charge felt by the outer electrons is reduced.
What is an inner shell electron?
These are the electrons that are not the valence electrons and are also known as core electrons.See the Related Questions and Web Links to the left for more information about valence and core electrons.
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

Do Electrons from inner shells link up to form compounds?
No, only outer shell electrons participate in chemical bonds.
