Photochemical Reactions (Hydrogen-Bromine

2020-4-17  Hence, we can conclude that the rate of hydrogen-bromine reaction is directly proportional to the intensity of absorbed radiation. It is also worthy to note that the quantum yield of the hydrogen-chlorine reaction is much higher than that of hydrogen-bromine reaction which may simply be attributed to the exothermic nature of the second step in ...

What Are the Seven Diatomic Elements? - Reference

2020-3-25  Follow Us: The seven diatomic elements are hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine and iodine. According to Princeton, diatomic molecules are molecules composed of only two atoms of either the same or different chemical elements. Five of the diatomic elements occur naturally as a gas. These include hydrogen, nitrogen, oxygen ...

Why f2 and Cl2 are gases Br2 is a liquid and I2 is a solid ...

2019-5-23  Why is chlorine Cl2 a gas at room temperature bromine Br2 a liquid and iodine I2 a solid? At 25oC, chlorine (Cl2) is a gas whereas bromine (Br2) is a liquid. As the elements are cooled, the kinetic energy of the Cl2 and Br2 molecules decreases and the London forces are strong enough to overcome the kinetic energy and hold the molecules in a solid.
