After Break Review

Front

What is a property of metals?

Back

Malleable: Metals can be hammered or pressed into shapes without breaking.

Front

What is an alloy?

Back

An alloy is a mixture of metal atoms with one or more other types of atoms.

Front

What happens to the particles of a solid as it is heated?

Back

They gain vibrational energy, causing them to move more freely.

Front

How do ionic compounds compare to molecular compounds in terms of melting and boiling points?

Back

Ionic compounds have higher melting and boiling points than molecular compounds.

Front

What are dispersion forces?

Back

Dispersion forces are the weakest type of intermolecular forces.

Front

Define malleability in metals.

Back

Malleability is the ability of a metal to be deformed under compressive stress.

Front

What is the difference between a pure metal and an alloy?

Back

A pure metal consists of only one type of atom, while an alloy is a mixture of different types of atoms.

Front

What is the significance of ionic bonds in ionic compounds?

Back

Ionic bonds are strong attractions between oppositely charged ions, leading to high melting and boiling points.

Front

Explain the term 'vibrational energy' in the context of solids.

Back

Vibrational energy refers to the energy that particles in a solid gain as they vibrate more vigorously when heated.

Front

What are the characteristics of ionic compounds?

Back

Ionic compounds are typically solid at room temperature, have high melting and boiling points, and conduct electricity when dissolved in water.
