Metallic Bonds

Front

What is a metallic bond?

Back

A metallic bond is a type of chemical bond that occurs between metal atoms, characterized by a 'sea of electrons' that are free to move around, allowing for conductivity and malleability.

Front

Why are metals good conductors of electricity?

Back

Metals are good conductors of electricity because the sea of electrons can move freely, allowing a negative charge to push these electrons in one direction, creating an electric current.

Front

What is meant by the term 'sea of electrons'?

Back

The 'sea of electrons' refers to the collection of free-floating electrons in a metal that are not bound to any specific atom, allowing for conductivity.

Front

What charge do metal ions typically have?

Back

Metal ions typically have a positive charge due to the loss of one or more electrons.

Front

What property of metals allows them to be shaped into wires?

Back

The malleability of metals allows them to be shaped into wires without breaking.

Front

How does the structure of metals contribute to their strength?

Back

The closely packed arrangement of metal atoms and the presence of the sea of electrons contribute to the strength and durability of metals.

Front

What is the relationship between metallic bonds and thermal conductivity?

Back

Metallic bonds allow for the free movement of electrons, which also facilitates the transfer of heat, making metals good conductors of thermal energy.

Front

What happens to the electrons in a metallic bond when an electric field is applied?

Back

When an electric field is applied, the free electrons in the metallic bond move towards the positive side, creating an electric current.

Front

What is the significance of the term 'ductility' in relation to metals?

Back

Ductility refers to the ability of metals to be stretched into wires without breaking, a property that arises from metallic bonding.

Front

How does the presence of impurities affect the properties of metals?

Back

The presence of impurities can disrupt the regular arrangement of atoms in metals, affecting their conductivity, strength, and malleability.
