Bismuth is considered to be a poor metal having an atomic number of 83. The metal carries a charge of +3 . Bismuth has been in existence since ancient times.
The valency of bismuth is 3
3+
-2
Fluorine will gain one electron to form F- (or fluoride) ion. Fluoride ion has a charge of -1.
Each separate chlorine ion will have a charge of 1-. This is because chlorine has 7 valence electrons, so it needs one more electron to become stable.
F^-1 and Br^-1
Fluorine forms a 1- ion because it has 7 electrons in its outer shell, this is not very stable. What is stable is a full outer shell of 8 electrons. So a fluorine atom will take an electron (which carries a 1- charge) from another atom to complete this so-called octet.

Fluorine will gain one electron to form F- (or fluoride) ion. Fluoride ion has a charge of -1.
Neon does not form any compounds or ions.
The phosphide ion is stable
it is dark
Each separate chlorine ion will have a charge of 1-. This is because chlorine has 7 valence electrons, so it needs one more electron to become stable.
selenium has a -2 charge. when it forms a compound with another atom the charge of the compound should be zero unless it has a cahrge in its equation. when compounds form they try to be in the most stable state which is when all their valance elctrons are full which means the charge is zero.
Anything that is unstable is more reactive, and anything that is stable is less reactive. Since a charged ion requires energy to maintain its charge, it is LESS stable and thus MORE reactive.
Well the charge on the compound would be stable (0) when bonded, because the Calcium has given it's electrons to the Oxygen atom. But the charge on the calcium ion itself would be 2+
An electron has a charge of -1. When a Sodium (Na) atom loses one electron, it loses a negative and becomes a stable Sodium ion with a charge of +1.
