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.

What charge does bromine form in compounds?
The charge that bromine forms in compounds is -1. This is because it is a type of halogen that takes electrons to fill its outer shell.
What does the two tell you in MgBr2?
This means that there are two bromines in magnesium bromide, much like there are two hydrogens in water, H2O. This occurs because when magnesium forms an ion it has a charge of (+2), and when bromine forms an ion, it has a charge of (-1), Thus, it takes 2 bromines to neutralize the charge of the magnesium.
What has a larger radius a bromine atom or a bromine ion?
That depends: is it a positive ion (Br+) or a negative ion (Br-)? An ion with a charge of +1 has one less electron than the element would have normally. An ion with a charge of -1 has one more electron than normal. It seems kind of strange that -1 means one more, and +1 means one less, but that's because an electron has a charge of -1, so if there is one less electron than is needed to keep the atomic charge balanced, the charge will be positive by 1. Cations (pronounced cat-ions, not cashons), ions with a positive charge and therefore fewer electrons than the neutral atom, have a smaller atomic radius than the neutral atom. Anions, ions with a negative charge and therefore more electrons than usual, have a larger atomic radius than the neutral atom. So a bromine cation would have a smaller radius, and a bromine anion would have a larger atomic radius. NOTE: when referring to a neutral atom, the atom is of THE SAME ELEMENT as the ion. Otherwise, the comparison is not necessarily true.
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 is the ion name for bromine?
Bromide
What is the charge on the ion for bromine?
-1
How many Li ions are needed to combine with one bromide ion?
Bromine has -1 charge and Lithium has +1 charge. Therefore,only one lithium ion is required to react with a bromine ion.
What is the charge for a bromine ion with 26 electrons?
A bromine ion with only 26 electrons is not possible. A bromine atom has 35 electrons and it can't loose 9 electrons.
When bromine atom gains one electron?
a bromide ion is formed, the ion formed has a -1 charge, and the ion formed is an anion
Indicate the charge on the bromide ion in the equation resulting in the ionic compound potassium bromide?
The charge of Bromine would be -1.
Valency of bromide?
Bromine forms anion. It gets a charge of -1 to form bromide ion.
What charge does bromine form in compounds?
The charge that bromine forms in compounds is -1. This is because it is a type of halogen that takes electrons to fill its outer shell.
What is the symbol of bromine ion?
The bromine ion is referred to as bromide, and it is Br^-
What does the two tell you in MgBr2?
This means that there are two bromines in magnesium bromide, much like there are two hydrogens in water, H2O. This occurs because when magnesium forms an ion it has a charge of (+2), and when bromine forms an ion, it has a charge of (-1), Thus, it takes 2 bromines to neutralize the charge of the magnesium.
Is bromine a atom or ion?
"Bromine" is the name of an atom or an element. The corresponding ion is named "bromide".
What is the correct formula for a lithium ion and bromine ion compound?
Lithium ion is Li+ and a bromine ion (called a bromide ion) is Br- and the compound formed from them would be LiBr.
Why does bromine form a -1 ion?
Bromine has seven electrons in its outermost energy level. It can get the stable electron configuration by getting one electron from another atom which makes the -1 charge.
