Bromine and krypton are both elements on the Periodic Table. They are both nonmetals that are found in nature as diatomic molecules (Br2 and Kr). Additionally, they both have relatively high atomic numbers and are part of the halogen group.
When bromine reacts to form an ion, it becomes isoelectronic with krypton. Both bromine (Br) and krypton (Kr) have 36 electrons in their neutral state. When bromine gains one electron to form the Br- ion, it now also has 36 electrons like krypton.
Bromine (Br) has 35 electrons, while Krypton (Kr) has 36 electrons. To have the same electron configuration as Krypton, Bromine would need to lose one electron.
Bromine: -7.2 °C Selenium: 220.8 °C Krypton: -157.4 °C So of the elements listed Kryption has the lowest melting point.
Bromine typically gains one electron to achieve a stable electron configuration in chemical reactions, forming an anion with a charge of -1. This allows bromine to achieve a full outer shell of electrons like the noble gas configuration of krypton.
Several elemental gases are not in the same period as lithium. These are: hydrogen helium chlorine argon bromine krypton xenon radon
Krypton is more similar.
No, bromine forms an ion with a charge of -1. An ion isoelectronic with krypton would have the same number of electrons as krypton, which is 36 electrons.

The nearest noble gas to bromine is krypton. Bromine is located in Group 17 of the periodic table, while krypton is in Group 18, making it the closest noble gas in terms of atomic number and position. Krypton has an atomic number of 36, whereas bromine has an atomic number of 35.
Bromine (Br) has 35 electrons, while Krypton (Kr) has 36 electrons. To have the same electron configuration as Krypton, Bromine would need to lose one electron.
Bromine loses its outermost electrons more easily than krypton since bromine is in Group 17 of the periodic table (halogens), which tend to gain an electron to achieve a stable electron configuration. Krypton, on the other hand, is a noble gas in Group 18 and has a full outer shell, making it less likely to lose electrons.
the noble gases, krypton, xenon and radon are larger than bromine
Bromine: -7.2 °C Selenium: 220.8 °C Krypton: -157.4 °C So of the elements listed Kryption has the lowest melting point.
The noble gas that comes before bromine is argon.

I do not think that Bromine behaves like Krypton in chemical reactions. Krypton is very unreactive due to the fact that it has a full stable set of valence electrons, and Bromine is extremly reactive and has high electronegativity because is does not have a full stable set of valence electrons. Although, I do suppose that if a Bromine atom were to become a negative ion (Br+1) by gaining another electron, it would act as if it were a Krypton atom.
