A sea of electrons. This is a very good description of the bonding in group 1 group 2 metals. A more advanced view for transition metals calls the sea of electrons an "sp electron gas" alongside covalent bonding involving d electrons. This accounts for the melting point trends in transition metals
electrons are free to move among many atoms
Covalent bonds can be best described as a sharing of electrons between atoms. This sharing creates a stable arrangement of electrons in the outer energy levels of the atoms involved.
Valence electrons are the outermost electrons in an atom that are involved in forming chemical bonds with other atoms. They determine the atom's reactivity and ability to form compounds. The number of valence electrons can also be used to predict an element's chemical properties.
Electronegativity is a measure of an element's ability to attract electrons towards itself in a chemical bond. The higher the electronegativity value of an element, the stronger its ability to attract and hold onto electrons.
A polar covalent bond best describes a bond formed between two unlike atoms. In this type of bond, electrons are shared unequally between the atoms, leading to a partial positive and partial negative charge on the atoms involved.

flow of electrons
The flow of electrons
A metallic bond is a type of chemical bond where electrons are free to move throughout the material, creating a sea of delocalized electrons that hold the metal atoms together. This results in properties such as high electrical and thermal conductivity, malleability, and ductility.
Sharing of electrons. Generally this involves pirs of electrons forming bonds.
energy levels
Electrons are transferred from one atom to another.
Depending on the arrangement of outer atoms, this molecule could be polar or nonpolar.
mobile electrons
Covalent bonds can be best described as a sharing of electrons between atoms. This sharing creates a stable arrangement of electrons in the outer energy levels of the atoms involved.
An electric circuit is best described as a loop. the flow of electrons
