ionic bonding Flashcards
1
Q
ionic bonds are between:
A
metal and non metal ions
2
Q
electrostatic attraction is between:
A
positively charged metal ions and negatively charged non metal ions
3
Q
why do ionic bonds have high melting points:
A
strong electrostatic attraction
4
Q
when and why are ionic bonds good electrical conductors
A
when molten or dissolved in water. ions carry electrical charge and are free to move
5
Q
when and why are ionic bonds bad electrical conductors
A
when solid. charged ions are present but in the lattice they have fixed possitions
6
Q
what form to ionic bonds take
A
regular crystal - ions arranged in lattice; forms regular crystal pattern and shape
