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.
The charge of Bromine (Br) as an ion is -1.
The bromide ion has a 1- charge.
Bromide ion= -1 charge
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.
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.
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.
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.
Bromide
-1
One lithium ion is needed to combine with one bromide ion to form lithium bromide (LiBr).
A bromine ion with only 26 electrons is not possible. A bromine atom has 35 electrons and it can't loose 9 electrons.
When a bromine atom gains one electron, it becomes a bromide ion (Br-). This ion has a full outer electron shell, giving it a stable electron configuration similar to a noble gas.
The bromide ion has a charge of -1. In the ionic compound potassium bromide (KBr), potassium has a charge of +1 to balance the -1 charge of the bromide ion.
Bromine forms anion. It gets a charge of -1 to form bromide ion.
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.
The bromine ion is referred to as bromide, and it is Br^-
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.
"Bromine" is the name of an atom or an element. The corresponding ion is named "bromide".
The formula for the compound formed between lithium ion (Li+) and bromine ion (Br-) is LiBr. Lithium being a group 1 element with a +1 charge and bromine being a group 17 element with a -1 charge, they combine in a 1:1 ratio to form a stable ionic compound.
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.
