Metallic Bonds

Front

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

Back

It's what we call all the free floating electrons in a metal.

Front

Which of the following is NOT a property of metals?

Back

Very brittle (breaks easily)

Front

Why are metals good conductors of electricity?

Back

A negative charge can easily push the sea of electrons in one direction, making a current.

Front

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

Back

Ductile.

Front

What property of metals allows them to conduct electricity?

Back

Conductive.

Front

What is the general structure of metallic bonds?

Back

Metallic bonds consist of positively charged metal ions surrounded by a 'sea of electrons'.

Front

How does the 'sea of electrons' contribute to the malleability of metals?

Back

The sea of electrons allows metal atoms to slide past each other without breaking the bond.

Front

What is malleability in the context of metals?

Back

The ability of a metal to be hammered or pressed into shapes without breaking.

Front

What is the significance of metallic bonding in the properties of metals?

Back

Metallic bonding gives metals their characteristic properties such as conductivity, malleability, and ductility.

Front

How does temperature affect the conductivity of metals?

Back

As temperature increases, the conductivity of metals generally decreases due to increased atomic vibrations.
