metal structure, bonding and properties Flashcards
1
Q
3 properties of metals?
A
malleable
shiny
good conductors of electricity
2
Q
acid + metal?
A
salt + hydrogen
3
Q
metals contain what 2 things?
A
sea of delocalised electrons
GIANT ionic lattice of positive metal ions
4
Q
what is metallic bonding?
A
the electrostatic attraction between the positive metal ions and the negative delocalised electrons
5
Q
what type of boiling points do metals have?
A
high
6
Q
why do metals have high boiling points?
A
the metallic bonding is usually very strong so lots of energy is needed to break it
7
Q
how do metals conduct electricity?
A
the delocalised electrons are free to move through the lattice
8
Q
why are metals malleable?
A
the layers of metal ions can slide easily over eachother
