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

Why is iodine a solid at room temperature and chlorine a gas despite being in the same group.

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

What elements form diatomic gases. That s why we can observed these elements at different physical states at room temperature. Their group number only describes the number of electrons they have in their outer shell. 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.

Bromine and iodine are halides. 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. Bromine is a liquid at room temperature and iodine is a solid. We can further relate this to their physical states solid has the greatest molecular interactions while gas has the weakest molecular attractions.

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. In other words they are chemical elements found in group 17 of the periodic table of elements. At ordinary temperature and pressure chlorine is because a gas bromine is a liquid and iodine is a solid because. It has a low value of electronegativity.

Iodine is a solid at room temperature because 500 likes. The key difference between bromine and iodine is that bromine is a liquid at room temperature while iodine is a solid at room temperature. Bromine is a liquid at room temperature and iodine is a solid. As iodine has a higher atomic number than chlorine it also has more electrons in its electron shells.

At room temperature is chlorine a. The iodine that you buy in a store as a liquid has been mixed with other chemicals for easy use. Chlorine cl2 has the lowest mm thus weakest ldf while iodine i2 has the highest mm thus strongest ldf.
