Which metal Cannot form multiple ions?
Which metal Cannot form multiple ions?
For example, NO 3− is nitrate and NO 2− is nitrite. The halogens and some of the transition metals form more extensive series of oxoanions with as many as four members….Metals that form more than one cation.

What metals form multiple ions?
A few elements, all metals, can form more than one possible charge. For example, iron atoms can form 2+ cations or 3+ cations. Cobalt is another element that can form more than one possible charged ion (2+ and 3+), while lead can form 2+ or 4+ cations.
What other metals that also form only one ion?
Rb, K, Cs, Li, Al, Mg, Ba, Sr, Na, Zn,Ca and Ag are the elements, that is the metals that form only one type of ion, whose charge is invariant from one compound to another.
Do the Roman numerals in the names in Model 3 relate to the number of cations or number of anions in the formula unit?
Do the Roman numerals in the names in Model 3 relate to the number of cations or number of anions in the formula unit? Support your answer by citing two specific examples. The Roman numerals do not relate to the number of cations or anions.

When to write formulas for multivalent metal compounds?
Since multivalent metals can often form multiple compounds with the same anion, a means is required to differentiate between multiple compounds with the same constituent elements (like the iron and oxygen compounds in question 3, above) when writing formulas for multivalent metal compounds.
What happens when main group metal ions dissolve in water?
Salts of main group metal ions dissolve in water to form aqueous solutions. When we let the water evaporate, we get back the original starting material, NaCl ( s ). Salts of the transition-metal ions can display a very different behavior.
