METALLIC BONDING

In which part of the periodic table are metals mostly found?

• At the top

• On the left

• On the right

Which of these describes the arrangement of particles in a metal?

• Closely packed electrons with delocalised ions

• Alternating layers of metal ions and electrons

• Layers of metal ions surrounded by delocalised electrons

How many electrons are delocalised in a metal?

• 1

• 2

• As many as are in the outer shell

What does a metallic bond consist of?

• Forces between metal ions and delocalised electrons

• Pairs of metal atoms joined together by strong bonds

• Forces between oppositely charged metal ions

Which of the following is NOT a property of a typical metal?

• Poor conductor of electricity

• High melting point

• Shiny

What does 'malleable' mean?

• Able to be drawn into wires

• Able to conduct electricity

• Able to be hammered into thin sheets

Which of these metals does NOT have a high melting point?

• Magnesium

• Mercury

• Silver

Why are metals ductile?

• Because the metal is arranged in layers

• Because the metal ions are closely packed

• Because the metal can conduct electricity

Why do metals conduct electricity?

• They have free-moving atoms

• They have free-moving ions

• They have free-moving electrons

Why do metals have high melting points?

• Metallic bonds are weak and metals have a simple structure

• Metallic bonds are strong and metals have a lattice structure

• Metallic bonds are strong and metals have a simple structure
