Their group number only describes the number of electrons they have in their outer shell.
Chlorine iodine at room temperature.
Actual boiling point is.
2 9 recall the colours and physical states of the elements at room temperature chlorine gas pale green bromine liquid red brown evaporates to form brown gas iodine solid black sublimes to form purple gas 2 10 make predictions about the properties of other halogens in this group reactivity decreases down the group color darkens down the group.
Iodine is further down group 7 than chlorine.
Above 700 c 1 300 f dissociation into iodine atoms becomes appreciable.
Explain why at room temperature fluorine and chlorine are gases bromine is a liquid and iodine is a solid.
Iodine iodine physical and chemical properties.
Iodine is a nonmetallic nearly black solid at room temperature and has a glittering crystalline appearance.
As a result fluorine and chlorine are present as gases at room temperature bromine is a liquid and iodine is a gas.
Why is iodine a solid at room temperature and chlorine a gas despite being in the same group.
