12/19/2023 0 Comments Atomic radius of bromine![]() Hence, most commonly the chlorine atom loses one electron during a chemical reaction. The electron arrangement in chlorine atom is 2, 8, 18, 7.Bromine is a reactive nonmetal and hence it is not found in a free state in nature.Chemical properties of BromineĬhemical properties of bromine are mentioned below. 79Br has an abundance of 51% and 81Br has an abundance of 49%. And out of them, only 2 isotopes are stable ( 79Br and 81Br). Bromine has a very less number of isotopes.The atomic mass of bromine is 79.904 u and its density is 3.12 g/cm 3.The melting point of bromine is -7.2 ☌ and its boiling point is 58.8 ☌.The bromine vapors have a very pungent odour and it can also irritate our eyes.Bromine is a nonmetal in liquid state having a reddish brown color.Physical properties of bromine are mentioned below. The physical and chemical properties of bromine element are mentioned below. Pure bromine is a toxic element and it can also cause burns on skin.Bromine atoms are more destructive to the ozone layer as compared to that of chlorine atoms.Bromine is approximately 3 times denser than water.Out of all the elements of halogen group, bromine is the 3rd lightest element.The abundance of bromine in the earth’s crust is around 2.4 ppm by weight.Bromine is the 44 th most abundant element found from the earth’s crust.The name “bromine” was derived from the Greek word “bromos”.Bromine and mercury are the only elements that are in liquid state at standard temperature and pressure.Bromine is the only nonmetal that exists in a liquid form at room temperature.Interesting facts about bromine element are mentioned below. So the last electron of bromine enters the p-subshell or p-orbital. The simple answer: The elements will lie in the s, p, d or f block will completely depend upon the subshell in which the last electron will enter.įor example the electron configuration of bromine is 3d 10 4s 2 4p 5. How can you determine the blocks-wise position of elements? Orthorhombic Melting point of Bromine 265.8 K or -7.2 ☌ or 19 ☏ Boiling point of Bromine 332 K or 58.8 ☌ or 137.8 ☏ Density of Bromine 3.12 g/cm 3 Main isotope of Bromine 79Br (51%) and 81Br (49%) Who discovered Bromine and when?Īntoine Jerome Balard and Carl Jacob Lowig (in 1825) CAS number īefore knowing this reason, first of all I want to ask you a simple question.

Bromine Element (Br) Information Appearance of Bromine So if you want to know anything about Bromine element, then this guide is for you. In fact, the table mentioned below is the perfect information box (Which gives you every single detail about the Bromine element in Periodic table.) Because a bromine atom has one more full shell than a chlorine atom, it has more shielding which means the attraction between the nucleus and an electron is weaker.Īlthough the bromine nucleus is more positively charged than the chlorine nucleus, the increase in the radius and the extra shielding in the bromine atom outweigh this factor, which means that an electron is more easily attracted into the outer shell of a chlorine atom than that of a bromine atom, so chlorine is more reactive.This is a SUPER easy guide on Bromine element. The number of full electron shells between the nucleus and the electron also affects the strength of the attraction – this is called shielding. The bromine nucleus therefore has to attract an electron from further away, and this greater distance means the electron is attracted less strongly.ģ. This makes the radius (the distance from the nucleus to the outer shell) of the bromine atom larger than that of the chlorine atom. The bromine atom has one more electron shell than the chlorine atom. This means that a bromine nucleus has a stronger attraction for an electron than a chlorine nucleus.Ģ. ![]() ![]() A bromine atom has 35 protons but a chlorine atom only has 17. Protons are positively charged and attract negatively charged electrons. ![]() There are three factors that affect how easily an electron is accepted:ġ. When they react, both chlorine and bromine need to accept an electron into their outer electron shell to complete the shell and form chloride and bromide ions.
