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.
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.
What element do most of the polyatomic ions have in the formula?
Examples: oxygen, sulfur, carbon, phosphorus etc.
Are a vast majority of polyatomic ions cations?
No. Most polyatomic ions are anions.
What are the usual endings for the names of polyatomic ions?
The names of most polyatomic ions end in -ite or -ate.
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 characteristics is shared by most simple polyatomic ions?
They are Anions.
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.
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 is oxo?
A polyatomic ion is an ion containing two or more atoms, usually of more than one element. An example is the nitrate ion. (NO−3 - ) This is 1 nitrogen with 3 oxygen's attached and bears a charge of 1-. The most common polyatomic ions are anions that contain oxygen attached to some other element called an oxoanion and are typically combinations of oxygen with a nonmetal. For a given nonmetal, there are often two or more common oxoanions SO32-(sulfite ion) 1 sulfur 3 oxygens and a charge of 2-,

Do metals make up ionic compounds?
They don't entirely make up ionic compounds. Most ionic compounds contain a metal and at least one nonmetal element, with the metal forming the positive ion. However in a few cases an ionic compound may be made up entirely of nonmetals forming polyatomic ions (e.g. ammonium nitrate, NH4NO3).
