[Ar]3d104s24p5
The noble gas configuration for bromine is [Ar] 3d10 4s2 4p5. This configuration represents the electron arrangement of bromine with a filled inner electron shell similar to that of the noble gas argon.
The noble gas configuration for Bromine (Z = 35) is [Ar] 3d10 4s2 4p5. This configuration represents the electron arrangement of Bromine and is based on the electron configuration of Argon.
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.
The electron configuration of bromine is: [Ar]4s23d104p5.
The noble gas shortcut for Br (Bromine) is [Ar] 4s2 3d10 4p5. The noble gas Argon (Ar) has an electron configuration of 1s2 2s2 2p6 3s2 3p6, which is the closest noble gas with a lower atomic number to Bromine.
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).
The element with the noble gas configuration Ar 4s2 3d10 4p5 is bromine (Br), which has an atomic number of 35. It is in the halogen group and has seven valence electrons, making it reactive.
The noble gas that comes before bromine is argon.
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
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.
Bromine can form a -1 ion by gaining one electron to achieve a stable electron configuration. This allows bromine to attain a full outer electron shell, similar to the electron configuration of a noble gas, making it more stable.
The noble-gas configuration Ar 4s² 3d¹⁰ 4p⁵ corresponds to the element bromine (Br). Bromine has an atomic number of 35, indicating it has 35 electrons. In its electron configuration, the outermost shell contains 7 electrons (4s² 3d¹⁰ 4p⁵), which aligns with its placement in group 17 of the periodic table, where it is classified as a halogen.
