At-
Not O3, which is ozone. But O-2 is the most common ion of oxygen.
Astatine can react with iron, forming astatide ions (At-) in aqueous solutions. This reaction is rare and not well studied due to astatine's scarcity and radioactivity. The astatine ion would likely displace another halogen ion in a salt with iron, similar to reactions with other halogens like iodine.
The most common Selenium ion is Se2- the selenide ion. It is in the same group as oxygen and its most common ion in the oxide ion O2-.
The Chemical Formula for Potassium Ion is K+.
The three most common such ions probably are sulfate, with the formula SO4-2, chromate, with the formula CrO4-1, and perchlorate, with the formula ClO4-1.
Astatine is an element with the symbol At.
The ionic formula for calcium astatide is CaAt2, because calcium typically forms 2+ cations and astatine typically forms 1- anions, requiring two astatine ions to balance the charge of one calcium ion.
Not O3, which is ozone. But O-2 is the most common ion of oxygen.
Astatine can react with iron, forming astatide ions (At-) in aqueous solutions. This reaction is rare and not well studied due to astatine's scarcity and radioactivity. The astatine ion would likely displace another halogen ion in a salt with iron, similar to reactions with other halogens like iodine.
The charge on the astatide ion is -1. Astatide is the anion of astatine, which belongs to the halogen group in the periodic table and typically gains one electron to achieve a full outer shell configuration.
The chemical formula of a sodium ion is Na+, while the chemical formula of a fluoride ion is F-.
The most common Selenium ion is Se2- the selenide ion. It is in the same group as oxygen and its most common ion in the oxide ion O2-.
The common simple ion is S-2 and the most common polyatomic ion is probably SO4-2.
Formula: NO2-
Formula: Pb2+
The formula for ammonium ion is NH4+ and the formula for oxalate ion is C2O4^2-.
The hydroxide ion's chemical formula is [OH]-
