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 is part of an atom that move around the outer shells?
the valence electrons
What is the value of n for the valence shells of as?
The value of 'n' for the valence shells is the number of shells that specific atom has
What are valence shells?
Electrons in the outermost orbitals of an atom. They determine the chemical reactivity of an atom and are the primary electrons that participate in chemical reactions.

How many valence shells in radium?
Radium has seven electron shells; the valence of radium is 2+.
How many valence electrons are in Cl atom?
There are 7 valence electrons in a chlorine atom. The atomic number of chlorine is 17, which means it has an electron configuration of 2,8,7. This shows it has 3 shells of electrons, with 7 in the outer level.
What are cores?
An atom stripped of its valence electrons, so that its remaining electrons are all in closed shells.
How many valence electron does Sr have?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
How do atom form chemical bond?
Around the nucleus of atoms circulate electrons. They are in shells. The electrons in empty shells are called valence shells. Now, if a shell isn't full, only partly, an atom will want to fill it. Hence, it will connect with an atom with too many electrons. Nature in general abhors energy and will always try to minimize it. It is energetically favorable for atoms with too many electrons to bond with atoms with too few in the valence orbit/shell. Sometimes it is more energetically favorable to share electrons. This type of bond is a covalent bond.

If magnesium has two valence electrons while chlorine has seven how many chlorine atoms are needed to form an ionic bond with magnesium?
One chlorine atom will form an ionic bond with one magnesium atom. The magnesium will donate its two valence electrons to the chlorine atom, filling both of their valence electron shells.
