Why is roman numeral placed after the name of most transition element ions?
to present the oxidation numbers of transition elements according to IUPAC System.
What are meaning number one?
It is the multiplicative identity of numbers in most sets. It can also mean the "most important" element or member.

Can a line graph contain more than one line?
Most definitely there can be several lines.
What is the most probable ion formed from AI?
AI is not an element or compound and so cannot form an ion.
What element do most of the polyatomic ions have in the formula?
Most polyatomic ions contain oxygen as one of the elements in their formula. This is because oxygen commonly forms stable ions with other elements.
Do Polyatomic ions always contain oxygen?
In most of the cases it is true but SCN- , Transition metals complex ions and some organic poly atomic ions do not contain oxygen.
Are a vast majority of polyatomic ions cations?
No. Most polyatomic ions are anions.
Are polyatomic ions positively charged?
Most polyatomic ions have a negative charge. There are only 2 positive polyatomic ions; Mercury(I) ion and Ammonium ion. False.
Characteristic is shared by most simple polyatomic ions?
They are anions
What polyatomic ions has the most atoms per formula unit?
The polyatomic ion with the most atoms per formula unit is the peroxydisulfate ion, ( \text{S}_2\text{O}_8^{2-} ), which contains a total of 10 atoms (2 sulfur and 8 oxygen atoms). Other complex polyatomic ions, such as certain phosphate or silicate ions, can also contain a large number of atoms, but peroxydisulfate is notable for its high atom count in a single formula unit.
Polyatomic ions always carry a positive charge?
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.
What are the usual endings for the names of polyatomic ions?
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.
How are polyatomic ions usually charged?
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.
Which of these pairs of elements is most likely to be part of a polyatomic ion?
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-).
What polyatomic ions are in soda?
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.
What characteristics is shared by most simple polyatomic ions?
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.
