Down the group melting point
Did you know?
WebWe can identify a trend in the melting points of group 1 elements: the melting point decreases as you go down the group from top to bottom. As the atomic radius increases down the group, the delocalised electrons making up the metallic bond get further from the nucleus so the metallic bond gets weaker and easier to weaken as you go down the group.
