Metallic Bond and Properties of Metals

Front

What is a metallic bond?

Back

A bond among metals that involves sharing of electrons between atoms in the entire metal.

Front

What are the characteristics of metallic bonding?

Back

1. Atoms in metal form metallic bonds. 2. Outer electrons are distributed throughout the solid metal. 3. Sea of electrons or delocalized electrons.

Front

What is malleability?

Back

The ability to be hammered, pressed, or rolled into thin sheets without breaking.

Front

What is ductility?

Back

The ability to undergo significant deformation before rupture or breaking.

Front

Why do metals have high melting and boiling points?

Back

Due to the strong electrostatic forces between the sea of electrons and cations.

Front

How do metals conduct electricity?

Back

Metals conduct electricity because delocalized electrons move towards the positive terminal when a potential difference is applied.

Front

What happens to the kinetic energy of electrons when heat is applied to a metal?

Back

The kinetic energy of the electrons increases and is transmitted through the sea of delocalized electrons.

Front

What are alloys?

Back

A mixture of two or more elements, where at least one is metal, often with superior properties compared to their component elements.

Front

What is the role of delocalized electrons in metals?

Back

Delocalized electrons allow metals to conduct heat and electricity.

Front

What is the difference between ionic, covalent, and metallic bonds?

Back

Ionic bonds occur between a metal and a nonmetal, covalent bonds occur between nonmetals, and metallic bonds involve delocalized electrons and positively charged metal ions.
