ionic bonding Flashcards
1
Q
what is ionic bonding
A
strong electrostatic forces of attractions between oppositely charged ions
2
Q
what is a simple molecule substance
A
has a finite number of atoms
e.g. fullerenes
3
Q
what is a giant molecule substance
A
has a infinite number of atoms
e.g. graphite
4
Q
how does an ionic bond occur
A
a transfer of electrons forming positive and negative ions
5
Q
what properties do ionically bonded compounds have
A
high melting points due to strong electrostatic forces of attraction
conduct electricity when dissolved or molten as ions are not fixed in a lattice
mostly soluble - dissolve in polar solvents
6
Q
give an example of an ionically bonded substance
A
NaCl
a metal and a non metal
7
Q
what structure does an ionically bonded substance have
A
a giant ionic lattice
