IONIC BONDING Flashcards
1
Q
when are ions fomed
A
when electrons are transferred from one atom to another
2
Q
what is there a strong attraction between
A
positive and negative ions
3
Q
which structure do ionic compounds exist as
A
giant lattices
4
Q
properties of ionic compounds
A
high melting point - strong attraction between positive and negative ions - a lot f energy needed to seperate them
conduct electricity when molten or in solution but not when solid
ions carry charge
in a solid they are fixed by strong ionic bonds so cannot move
