Metallic Bonds

Conductivity

• The ability of a material to transmit energy, such as electricity, which results from the mobility of its valence electrons.

• The measure of a material's resistance to the flow of electric current.

• The process by which materials absorb and store electrical energy.

• The phenomenon where materials become magnetic when exposed to electric fields.

What is a Metallic Bond?

• The attraction between positively charged metal cations and free-moving valence electrons that holds a metal together.

• The force that holds atoms together in a covalent bond.

• The interaction between two non-metal atoms that share electrons.

• The repulsion between negatively charged electrons in a metal.

Cation

• A negatively charged ion

• A positively charged ion, specifically a metal atom that has lost one or more of its valence electrons.

• An atom with no charge

• A type of molecule that contains both positive and negative ions.

What is Malleability?

• A property of metals that allows them to be hammered or pressed into thin sheets without shattering.

• A measure of how easily a material can be stretched into a wire.

• The ability of a material to conduct electricity.

• A characteristic of materials that allows them to return to their original shape after deformation.

Valence Electrons

• The electrons in an atom's outermost energy level, which are free to move throughout the structure of a metal.

• Electrons that are tightly bound to the nucleus and do not participate in bonding.

• Electrons that are found in the inner shells of an atom and are not involved in chemical reactions.

• The total number of electrons in an atom, including those in all energy levels.

What is the definition of Crystal Structure?

• The orderly, repeating, three-dimensional arrangement of cations that forms the lattice within a solid metal.

• A random arrangement of atoms in a solid.

• The process of melting a solid into a liquid.

• A type of chemical bond between two atoms.

What is the Sea of Electrons Model?

• A model for ionic bonding where electrons are transferred between atoms.

• A model for covalent bonding where electrons are shared between atoms.

• A model for metallic bonding where metal cations are arranged in a lattice and immersed in a sea of mobile electrons.

• A model for molecular bonding where molecules are held together by van der Waals forces.

Core Electrons

• The outer-shell electrons involved in chemical bonding.

• The inner-shell electrons of an atom that are not involved in chemical bonding and remain part of the metal cation.

• Electrons that are free to move in a conductor.

• Electrons that are lost during ionization.

What is Ductility?

• A physical property of metals that allows them to be stretched or drawn into wires without breaking.

• A measure of a material's resistance to deformation under stress.

• The ability of a material to conduct electricity.

• A property that describes how easily a material can be melted.

Electrostatic Attraction

• The force between oppositely charged particles, such as the attraction between positive metal cations and negative delocalized electrons.

• The force that repels particles with the same charge.

• The attraction between neutral particles due to induced dipoles.

• The gravitational force acting between charged particles.
