- fluorine-yellow gas/MP=-220 degrees/BP=-88 degrees
- group 7- the halogens
- bromine-orange liquid/MP=-7 degrees/BP= 59 degrees
- chlorine-green gas/MP=-101 degrees/BP=-55 degrees
- iodine-purple solid/MP=114 degrees/BP= 184 degrees
- fluorine is more reactive that iodine because the outer electron is closer to the positive nucleus.there is more barrier electron shells therefore the attraction is weaker.
- a displacement reaction is when a more reactive halogen displaces a less reactive halogen
- all of the halogens are non-metals,dont conduct electricity,poisonus and smelly,and are brittle when solid
- group 7- the halogens
