"The atoms in polyatomic ions such as hydroxide ion, ammonium ion and sulfate ion, are held together by covalent bonds" Link: http://www.cartage.org.lb/en/themes/sciences/chemistry/inorganicchemistry/Informationbonding/CovalentBond/CovalentBond.htm
I'm pretty sure it's an ionic bond, but I might be wrong.
The bonds in polyatomic ions are covalent although they may be quite polar.
A covalent bond.
Covalent Bonding.
Covalent Bonding
A covalent bond
Iron (III) fluoride has ionic bonds. No compound is any kind of bond.
A covalent bond.
Sodium chloride has an ionic bond.
ClO4 is not a compound, it exists as ClO4-, which is a polyatomic ion called the perchlorate ion. Some positive ion such as potassium or ammonium must be present to balance the charge and form a compound.
Covalent bond
There is no K-O bond in KOH as this is an ionic compound formed between the cation, K + and the polyatomic anion, OH - So, the electronegative difference here causes this ionic bond to form by attraction in whole as shown above.
polyatomic
A ionic bond between the cation,Na +and the polyatomic anion hydroxide,OH -to form, sodium hydroxide.
Covalent bond exists
hydroxide is a polyatomic ion (OH[superscript -])
Only covalent bonds form a molecule. Ionic bonds form an ionic compound.
the only kind of bonding happens when an electronegative atom (such as aluminum) attracts the electrons of another atom and they combined and form a compound
what is the oxidation number for phosphate
The cation,K +and the anion,Br -form the ionic compound,KBr==============Potassium bromide
Any chemical compound between uranium and argon.
Generally a metal with a nonmetal forms an ionic bond. Sodium is a metal and bromine is a nonmetal, so they will form an ionic bond, forming the compound sodium bromide, NaBr.
Based on it's electronegative difference the kind of bond present in the compound OF2 is a Polar covalent bond.
