• To represent a metallic solid or alloy using a model

• To understand the chemical reactions of metals

Which type of bonding is found in metals and their alloys?

• Hydrogen bonding

• Metallic bonding

• Covalent bonding

• Ionic bonding

What results in good electrical conductivity in metals?

• The arrangement of atoms

• The formation of ions

• The presence of covalent bonds

• The cloud of free electrons

What are alloys?

• Mixtures of gases

• Pure metallic elements

• Mixtures of metals or a metal and another element

• Solutions of metals in water

Which of the following is an example of an alloy?

• Oxygen

• Steel

• Sodium

• Chlorine

What is a substitutional alloy?

• An alloy with gaseous elements

• An alloy with elements of similar sizes

• An alloy that is made up of only one element

• An alloy with elements of different sizes

What is an interstitial alloy?

• An alloy with elements of similar sizes

• An alloy with elements that are gases

• An alloy with elements of significantly different sizes

• An alloy that changes color when heated

Why does steel not corrode easily?
