Chlorine Iodine At Room Temperature

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.

Chlorine iodine at room temperature.

Asked may 3 2020. This means that it will be solid at room temperature. Explain why at room temperature fluorine and chlorine are gases bromine is a liquid and iodine is a solid. Their group number only describes the number of electrons they have in their outer shell.

Iodine is a nonmetallic nearly black solid at room temperature and has a glittering crystalline appearance. The table shows the colour and physical states. Iodine is further down group 7 than chlorine. Explain why at room temperature fluorine and chlorine are gases bromine is a liquid and iodine is a solid.

Above 700 c 1 300 f dissociation into iodine atoms becomes appreciable. The molecular lattice contains discrete diatomic molecules which are also present in the molten and the gaseous states. Check approved by enotes editorial list cite. Iodine iodine physical and chemical properties.

As a result fluorine and chlorine are present as gases at room temperature bromine is a liquid and iodine is a gas.
