Metals Flashcards
(10 cards)
What type of structures do metals have?
Giant structures of atoms with strong metallic bonding
What are the melting and boiling points of most metals?
High melting and boiling points
How are atoms arranged in pure metals?
In layers that can slide over each other
What property of pure metals allows them to be bent and shaped?
The ability of atoms to slide over each other
Why are pure metals often mixed with other metals or carbon?
To make alloys which are harder
What allows metals to conduct electricity?
Mobile delocalised electrons
How do mobile delocalised electrons contribute to thermal energy conduction in metals?
Energy is transferred by the mobile delocalised electrons
Fill in the blank: Pure metals are too soft for many uses, so they are mixed with other metals or carbon to make _______.
Alloys
True or False: Metals have weak metallic bonding.
False
What is the significance of strong metallic bonding in metals?
It takes lots of energy to break
