Except chloride, all others are polyatomic ions.
Ions made up of more than one atom are called polyatomic ions.
There are many polyatomic ions, but some common ones include sulfate (SO4^2-), nitrate (NO3^-), carbonate (CO3^2-), and hydroxide (OH^-). These ions consist of two or more atoms covalently bonded together with an overall charge.
There are a zillion. Simply put, a polyatomic ion is an ion with two or more atoms in it. (Polyatomic is "multi" atom.) The number "zillion" isn't specific, of course, but we might be able to use it here in the science section to make a point. The phosphate group, PO4-2, and the hydroxyl group, OH-, are just two of many, many polyatomic ions. A link can be found below to the Wikipedia article on polyatomic ions. You'll find a looong list of them there. Why not check it out?
No. Most polyatomic ions are anions.
Hydroxide ion: OH- Sulfate ion: SO4^2-
polyatomic ions are those ions which carry more than one atom,we can say that a group of atoms having single charge( which may be positive or negative) are polyatomic ions.
False. Polyatomic ions can carry either charge. For example, consider the sulphate ion - SO42- or the hydroxide ion, OH-. Negative polyatomic ions are, in fact, generally more common than positive ones.
Covalent bonding is predominantly within polyatomic ions.
They are not similar.
There are two such ions: Hydronium (H3O+) and hydroxide (OH-).
For example no3 or co3 are all polyatomic ions
