The bromide ion, which has a charge of 1-, has one more electron than a neutral bromine atom. Its electron configuration is isoelectric with the noble gas krypton, so it has 36 electrons. Its electron configuration is [Ar]3d10 4s2 4p6. I apologize that the superscripts are not working. I put a space between the different sublevels to make it easier to understand.

Does bromine form a cation or an anion?
Bromine (Br) forms a anion (negative charge) because it is a halogen, and it gains 1 electron. However, when it gains that electron (Br)- its name changes to Bromide ion.
What happens to bromine when bromine atom gains an electron and forms the bromide ion Br -?
Bromine becomes basic.
What elements make up potassium bromide?
Yes: KBr--------K+ + Br- Br- is the anion.
What is the correct formula for bromide ion?
The electronic configuration of bromine is [Ar] 4s2 3d10 4p5. It needs to gain just one more electron in its 4p shell to attain the stable noble gas structure, thereby incurring a single negative charge. Therefore the chemical formula for the bromide ion is Br-.
What is the charge of a bromine ion?
A bromine ion has a -1 charge. That's because it is a halogen, and it is an electron "borrower" which wants to steal an electron to "complete" its outer electron shell. When it snags an electron to fulfill that tendancy of atoms to attain inert gas electron configuration, it ends up with that "extra" electron and a -1 charge. This is typical of all halogens, those elements that make up the Group 17 elements.
Is Br- referred to as an anion?
Yes, the ion bromide (Br-) is an anion.
Does bromine form a cation or an anion?
Bromine (Br) forms a anion (negative charge) because it is a halogen, and it gains 1 electron. However, when it gains that electron (Br)- its name changes to Bromide ion.
What does bromide means?
Bromide is the name of the bromine anion (Br-)
What charge does a bromide ion have?
Br-, like the other halogens F-, Cl-, Br-, I-. They would obtain one electron to have noble gas electron configuration. Therefore, one negative charge.
Identify cation and anion for KBr?
Potassium bromide, KBr: K+ - cation, Br- - anion
What is the cation for aluminum and bromine?
Aluminium cation is 3+; bromide anion is Br-. The aluminium bromide is AlBr3.
What charge does a bromide anion carry?
Anions carry negative charges, Br-
What is the formula of anion in the ionic compound sodium bromide?
Na^(+) + Br^(-)= NaBr
What noble gas has the same electronic configuration as fluorine?
K+ and argon have the same electron configuration
What is the formula for bromide ion?
I'm not 100% sure but potassium bromide is only need one negative bromide ion therefore since potassium is positive one I'm guessing bromide is negative oneThe Bomide ion is Br-.Bromine has 7 electrons in its outer shell and takes on one extra electron to give it a noble gas configuration.
What is the charge associated with each side of the HBr molecule?
Hydroge is a cation (H+) and bromide is an anion (Br)-.
Does bromide contain oxygen?
No. The bromide ion (Br-) contains only a single atom of bromine with an extra electron.
