In metallic bonding, the valence electrons freely 'jump' from atom to atom, forming kind of an electron sea.
Your body is made of molecules which are made of atoms. All atoms have electrons.

ATP molecules
The valence electrons are the only electrons that are involved in chemical bonding. These electrons can be shared or transferred. A simple rule of thumb is that atoms "strive" to attain the octet either by loss gain or sharing of electrons.
Glucose. Glucose is oxidized and oxygen is reduced here.
Valence electrons
Some materials can form polymers, molecules linked by shared electrons.
In covalent bonds, electrons are shared between atoms. This sharing of electrons allows for the formation of stable molecules by bringing atoms together through the attraction of their positively charged nuclei for the negatively charged electrons.
Molecules with bonds containing shared electrons are called covalent compounds. These compounds are formed when atoms share electrons in order to achieve a more stable electron configuration. Examples include water (H2O), methane (CH4), and carbon dioxide (CO2).
Electrons are shared when elements combine to form molecules. These are subatomic particles with a negative elementary electric charge.
Nonpolar molecules develop when there is an equal sharing of electrons between atoms within the molecule, resulting in a balanced distribution of charge. This leads to a lack of partial charges and overall symmetry within the molecule, making it nonpolar.
Atoms that share an equal number of electrons form covalent bonds. In these covalent bonds, each atom contributes the same number of electrons to the shared pair. This equal sharing of electrons results in stable molecules.
No, covalent molecules do not have oxidation numbers. Oxidation numbers are assigned to individual atoms in ionic compounds based on their electronegativity and sharing of electrons. In covalent molecules, electrons are shared between atoms, making it difficult to assign oxidation numbers.
lone pairs
In a covalent bond, the electrons in the outer energy levels (valence electrons) of the atoms are involved. These electrons are shared between atoms to achieve stability. The nuclei of the atoms are not directly involved in the sharing of electrons.
Electrons are most likely to be shared equally in nonpolar covalent bonds, where the atoms involved have similar electronegativities. This equal sharing occurs because neither atom has a strong pull on the shared electrons. Examples include diatomic molecules like oxygen (O2) and nitrogen (N2).
Covalent bonds are formed when two molecules share electrons. In a covalent bond, the shared electrons are attracted to the nuclei of both atoms, holding them together. This type of bond is strong and stable due to the sharing of electrons between the atoms.
