Metallic Bonding and Their Properties Flashcards
Metals consist of giant structures of atoms arranged in a ___________ pattern
Regular
Electrons in outer shell of metals atoms are _______________ and are _____ ____ _______ through the structure
Delocalised
Free to move
Most metals have high what?
Melting and boiling points
How are atoms arranged in pure metals?
What does this allow them to do?
The atoms are arranged in layers
They can be bent and shaped
Why are pure metals made into alloys?
When they are pure, they are too soft for many uses and alloys are harder
Why are metals good conductors of electricity?
Delocalised electrons carry electrical charge through the metal
Why are metals good conductors of thermal energy?
Energy is transferred by delocalised electrons
The atoms in pure metals can _______ ________ each other so they are malleable and _________
Slide across
Ductile
Atoms in alloys are different _______ so they can’t slide _______ each other. This makes them _______ and hard but not malleable or ductile
Sizes
Across
Strong
