to present the oxidation numbers of transition elements according to IUPAC System.
It is the multiplicative identity of numbers in most sets. It can also mean the "most important" element or member.

Most definitely there can be several lines.
AI is not an element or compound and so cannot form an ion.
Most polyatomic ions contain oxygen as one of the elements in their formula. This is because oxygen commonly forms stable ions with other elements.
No, polyatomic ions do not always contain oxygen. Polyatomic ions are composed of multiple atoms and can contain elements other than oxygen, such as sulfate (SO4^2-) or ammonium (NH4^+).
No. Most polyatomic ions are anions.
Polyatomic ions can be positively charged, negatively charged, or have a neutral charge. It depends on the specific composition and arrangement of the atoms within the polyatomic ion.
They are anions
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.
The usual endings for polyatomic ions are "-ate" and "-ite." The "-ate" ending signifies the ion with the larger number of oxygen atoms, while the "-ite" ending signifies the ion with one less oxygen atom.
It depends but most are negative, e.g. nitrite, sulfate, nitrate, sulfite, chlorite, phosphate, phosphite, permanganate, chromate, dichromate etc. There are however, polyatomic ions that are positively charged.
The pair of elements most likely to be part of a polyatomic ion is sulfur (S) and oxygen (O). This combination often forms polyatomic ions such as sulfate (SO4^2-) or sulfite (SO3^2-).
The most common polyatomic ions found in soda are carbonate (CO3^2-), bicarbonate (HCO3^-), and phosphate (PO4^3-). These ions are often present in ingredients like carbonated water and various additives used in soda production.
Most simple polyatomic ions have an overall charge due to the gain or loss of one or more electrons. They are typically made up of a small number of atoms bonded together and have a specific charge associated with their structure. These ions are generally stable and can participate in chemical reactions to form compounds.
A binary compound is composed of two different elements, while a polyatomic ion is a charged group of two or more atoms bonded together. Binary compounds do not form ions by themselves, while polyatomic ions have a net charge and act as a single unit in chemical reactions.
