Structure and Bonding in Metals Quiz

What explains the high melting and boiling points of metals?

• The presence of impurities

• The low density of metals

• The small size of metal atoms

• The giant structure of atoms and strong metallic bonding

Why are metals good conductors of electricity?

• They are shiny

• They have delocalised electrons

• They have a high density

• They have a regular atomic pattern

What is an alloy?

• A metal with impurities

• A metal mixed with another substance

• A mixture of metals with non-metals

• A pure metal

What is the role of delocalised electrons in metals?

• They increase the density of metals

• They prevent metals from rusting

• They allow metals to conduct electricity

• They make metals brittle

What is metallic bonding?

• Bonding between metal and non-metal atoms

• Bonding involving shared delocalised electrons in a giant structure

• Bonding that occurs only at high temperatures

• Bonding that makes metals non-conductive

Which property of metals is explained by their structure and bonding?

• Their color

• Their magnetic properties

• Their electrical conductivity

• Their ability to rust

What is the smallest part of an element that can exist?

• A molecule

• An atom

• A compound

• A crystal

What is the charge of an electron?

• Positive

• Variable

• Negative

• Neutral

What happens to the outer electrons in metal atoms?

• They are shared with non-metals

• They become localized

• They become delocalised

• They are lost completely

Why do metals have high boiling points?

• Because of strong metallic bonds

• Because they are dense

• Because they are shiny

• Because they are heavy
