Why Is Bromine A Liquid At Room Temperature And Iodine A Solid

Bromine is a liquid at room temperature and iodine is a solid.

Why is bromine a liquid at room temperature and iodine a solid.

At ordinary temperature and pressure chlorine is because a gas bromine is a liquid and iodine is a solid because. Bromine and iodine are halides. Bromine is a chemical element with the symbol br and atomic number 35. What elements form diatomic gases.

Chlorine cl2 has the lowest mm thus weakest ldf while iodine i2 has the highest mm thus strongest ldf. 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. We can further relate this to their physical states solid has the greatest molecular interactions while gas has the weakest molecular attractions.

That s why we can observed these elements at different physical states at room temperature. It has a low value of electronegativity. Its properties are thus intermediate between those of chlorine and iodine isolated independently by two chemists carl jacob löwig in 1825 and antoine jérôme balard in 1826. Their group number only describes the number of electrons they have in their outer shell.

In other words they are chemical elements found in group 17 of the periodic table of elements. Iodine is a solid at room temperature because 500 likes. It is the third lightest halogen and is a fuming red brown liquid at room temperature that evaporates readily to form a similarly coloured gas. The iodine that you buy in a store as a liquid has been mixed with other chemicals for easy use.

As iodine has a higher atomic number than chlorine it also has more electrons in its electron shells. The iodine that you buy in a store as a liquid has been mixed with other chemicals for easy use. At room temperature is chlorine a.
