Iodine forms the iodide ion. It has a charge of negative 1 (-1)
Iodine tends to form an anion. This is the iodide ion I-
There are compounds though where it actually forms a cation.
It gains one electron.
An iodine is an anion, or a negatively charged ion.
Tin itself is a neutral element and therefore neither a cation nor an anion. A single tin atom can form a cation by donating two or four of its electrons to more electronegative atoms. A single tin atom is not electronegative enough to form an anion, but together with oxygen atoms, a tin atom can form a polyatomic anion.
francium can form monovalent cations.
Potassium will most likely form a cation with a +1 charge.
anion. bromine is a non metal which gains an electron making it negative.
An iodine is an anion, or a negatively charged ion.
The cation is K+ and the anion is I-.
anion
Ag+ cation
Lithium form the cation Li2+.
when forces of attraction overcome forces of repulsion
is scandium a cation or an anion
Can an ionic compound ever consist of a cation-cation or anion- anion bond? Explain.
Can an ionic compound ever consist of a cation-cation or anion- anion bond? Explain.
Xenon is a bob,e gas, which means that it can't form any cation or anion by itself. If it joins any other element, then it can form an ion.
