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).

Does carbon have three electrons in its valence shells yes or no?
No, carbon has 4 valence electrons.
What is the number of valence electrons in selenium?
Selenium has 6 electrons in its outermost shell.
How many does hydrogen electrons in the outer shells?
Hydrogen has only one valence electrons.
Why are noble gases are non reactive?
They have filled valence shells. Atoms undergo chemical bonding in order to have filled valence shells by sharing electrons or transferring electrons. Because the noble gases already have filled valence shells, they have no need to react with other elements.
What do shells (energy levels) and valence electrons have to do with atoms combining to make molecules?
Valence electrons form the bonds between atoms in a molecule.
Do noble gases have valence shells?
Yes they have eight electrons in their valence shells. This is why they are not reactive. All elements have valence shells.
Can nonmetals gain electrons to fill their valence shells?
Yes, nonmetals generally gain electrons to fill valence shells.
Does carbon have three electrons in its valence shells yes or no?
No, carbon has 4 valence electrons.
What is different in number of shells in magnesium and sulphur?
There are no difference in the number of shells in magnesium and sulphur. Both elements contain 3 shells. However, the total number of electrons in the shells are different. Magnesium has 12 electrons in its shells whereas sulphur has 16 electrons in its shell. In addition, the electrons in the valence shell (outermost shell) are also different. Magnesium has 2 electrons in its valence shell whereas sulphur has 6 electrons in its valence shell.
What are valence and electrons?
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 is the number of valence electrons in selenium?
Selenium has 6 electrons in its outermost shell.
How many does hydrogen electrons in the outer shells?
Hydrogen has only one valence electrons.
How many valence shells in beryllium?
Beryllium has one valence shell containing two electrons.
As you move across a period elements have the same number of?
Electron shells
Are noble gases valence shells full of electrons.?
Yes, they're filled up with 8 electrons except for Helium which as only 2 valence electrons
Why are noble gases are non reactive?
They have filled valence shells. Atoms undergo chemical bonding in order to have filled valence shells by sharing electrons or transferring electrons. Because the noble gases already have filled valence shells, they have no need to react with other elements.
How many electrons would be in the valence shells of iodine and chlorine?
Both iodine and chlorine are halogens (group 17) and have 7 valence electrons.
