Chemical Bonding

Chemical Bonding

The interaction of electrons between elements to form compounds, resulting in a stable arrangement of electrons.

Ionic Bonding

A type of bonding that occurs between a metal and a non-metal, where electrons are transferred from the metal to the non-metal, resulting in the formation of an electrostatic attraction.

Covalent Bonding

two non-metals, electrons are shared between the atoms, shared pair as the bond

Octet Rule

gain, lose, or share electrons in order to achieve a full valence shell of eight electrons

Electronegativity

A measure of an atom's ability to attract electrons in a chemical bond.

Periodic Trends

The patterns observed in the properties of elements as they are arranged in the periodic table.

Ionic Bond

large difference in electronegativities between two elements, transfer of electrons.

Covalent Bond

A type of bond that occurs when there is a small difference in electronegativities between two elements, resulting in the sharing of electrons.

Electronegativity Difference

subtracting the smaller electronegativity value from the larger electronegativity value

EN > 1.7

ionic

EN < 1.7

covalent

ionic (metals)

large AR, less FOA, low IE (lose electrons)

ionic (nonmetals)

small AR, greater FOA, high IE (gains electrons)

covalent (nonmetals)

small AR, greater FOA, high IE (gains electrons)
