This is the loaning (by one atom) and the borrowing (by another atom) of a valence electron or electrons that creates a chemical bond. This type of bond is the ionic bond where one atom loans (or gives up) and the other borrows (or takes) an electron or electrons. In the other bond type, the covalent bond, the two atoms involved share electrons.
When an atom gives up loosely held valence electrons to another atom, bonding occurs.
An "ionic" bond.
Ions (cations or anions)
Cation
Ion.
Electrons in the outermost shell are valence electrons!
The number of valence electrons increases.
the valence electrons are shared.
It takes only one valence electron to form the calcium iodide compound.

Ionic bond
Electrons in the outermost shell are valence electrons!
The number of valence electrons increases.
No, they arent. Valence electrons are the amount of electrons the element has in its outermost shell. Electrons dont bond, they can either be shared or transferred. An ionic bond transfers electrons and a covalent bond shares electrons.
Mg donated two valence electrons to O.
Electrons are transferred when ionic bonds are formed.
