anion. bromine is a non metal which gains an electron making it negative.
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.
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.
Normally, bromine forms an anion, because it gains one electron to have a full octet, and is then negative. (Br1-) However, bromine can from a cation, as is the case when using N-bromosuccinimide (Br+ is given off).
francium can form monovalent cations.
Potassium will most likely form a cation with a +1 charge.
Bromine forms the Br- anion
Caesium form the cation Cs+.Bromine form the anion Br-.
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.
Aluminium cation is 3+; bromide anion is Br-. The aluminium bromide is AlBr3.
anion
Ag+ cation
Lithium form the cation Li2+.
The anion form of bromine, bromide, has eight valence electrons. Bromine normally has seven valence electrons, but gains to to form bromide.
Generally the ionic bond is formed between a metal and a nonmetal (cation and anion). As an example, sodium and bromine: sodium bromide, NaBr.
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.
