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 the meaning number one?
It is the multiplicative identity of numbers in most sets. It can also mean the "most important" element or member.

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?
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^+).
Are a vast majority of polyatomic ions cations?
No. Most polyatomic ions are anions.
Are polyatomic ions positively charged?
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.
Characteristic is shared by most simple polyatomic ions?
They are anions
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 is an oxoanion?
An oxoanion is a polyatomic ion that contains at least one oxygen atom and one or more other elements. These ions usually carry a negative charge and play important roles in various chemical reactions and compounds. Examples include nitrate (NO3-), sulfate (SO4 2-), and phosphate (PO4 3-).
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.
