How many electron does bromine borrow?
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.
How many electrons does a bromine atom need to gain in order to attain a noble gas electron configuration?
A bromine atom (Br) needs to gain one electron to achieve a full outer shell of electrons like a noble gas. This would give it the electron configuration of the noble gas krypton (Kr).
When bromine reacts to form an ion it becomes isoelectronic with?
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.
Which atom has the same electron shell arrangement of a ion of bromine?
An ion of bromine has the electron shell arrangement of 2, 8, 18, 7. Therefore, an atom that has the same electron shell arrangement would be one that has 35 electrons, such as the element bromine itself before it becomes an ion with a charge of -1.
What is the ground-state electron configuration expected for kr?
The ground-state electron configuration for krypton (Kr) is [Ar] 4s² 3d¹⁰ 4p⁶. This means that krypton has a total of 36 electrons distributed among its electron shells.
Which loses its outermost electrons more easily bromine or krypton?
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.

In a bromine atom which atomic orbitals contain the valence electrons?
* Ground state electron configuration:[Ar].3d10.4s2.4p6 so...4s and 4p
Bromine atoms always gain one electron when they become an ion which atom has the same number of electrons as a bromine ion?
An iodine atom has the same number of electrons as a bromine ion. Both elements belong to the halogen group and have seven valence electrons. When bromine gains one electron to become an ion, it will have a full outer shell with eight electrons, the same electron configuration as iodine.
When bromine reacts to form an ion it becomes isoelectronic with?
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.
Why is bromine very reactive while krypton is un reactive?
Krypton is a noble gas and has a full outer electron shell. Bromine on the other hand has 7 valence electrons, and being very electronegative, wants to accept an electron to satisfy its octet.
Which atom has the same electron shell arrangement of a ion of bromine?
An ion of bromine has the electron shell arrangement of 2, 8, 18, 7. Therefore, an atom that has the same electron shell arrangement would be one that has 35 electrons, such as the element bromine itself before it becomes an ion with a charge of -1.
How many electrons does BR need to achieve noble gas?
To achieve noble gas configuration, Bromine must gain one electron. In doing so, it obtains the electron configuration of Krypton. It's new complete electron configuration would be: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6.
How many electrons does Br need to acieve noble gas?
To achieve noble gas configuration, Bromine must gain one electron. In doing so, it obtains the electron configuration of Krypton. Its new complete electron configuration would be: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6.http://wiki.answers.com/How_many_electrons_does_BR_need_to_achieve_noble_gas#ixzz19YDVJEtp
How many electrons will Strontium gain or lose in forming a noble gas configuration?
Strontium, a group 2 element, will lose 2 electrons to attain a noble gas configuration because it will achieve a stable electron configuration similar to the nearest noble gas, which is krypton. Strontium has 38 electrons in its neutral state, while krypton has 36 electrons. By losing 2 electrons, Strontium becomes Sr2+, and its electron configuration is similar to krypton.
Noble gas configuration of bromine - ion?
The noble gas configuration for bromine's ion (Br-) is [Kr] 4d10 5s2 5p6, which is equivalent to the electron arrangement of krypton. Bromine gains an electron to achieve a stable octet configuration like a noble gas.
