It indicates the oxidation state.
Roman numerals are used to identify the oxidation state of transition metals with more than one possible oxidation state.
It is the oxidation state of the element, usually positive and used with metals. It can also be used without brackets and in superscript.
No, Na2O does not have a Roman numeral. When we talk about sodium oxide (Na2O), we are dealing with sodium and oxygen. We know that sodium has a +1 oxidation state in nearly everything it reacts with. You can pretty much bet on it. As it is essentially always going to combine in this +1 oxidation state, there is no need to differentiate that oxidation state from another one, which is what Roman numerals do.Oxygen has (almost always) a -2 oxidation state, and that means it takes two +1's to balance with a -2. Sodium, with its +1 oxidation state, will combine in a two-to-one ratio with oxygen, with its -2 oxidation state, to make the oxide.
Changing the Roman numeral IV to a different representation would simply alter its symbol, but not its value. In Roman numerals, IV represents the value 4. Changing it may involve using an alternative form like IIII or a different numerical system altogether, but the numerical value will remain the same.

Alaska joined the union January 3rd 1959 followed by Hawaii August 21, 1959. The first state to join the U.A was Hawai, Alaska joined a little later.
Roman numerals are used to identify the oxidation state of transition metals with more than one possible oxidation state.
They did not exist. Alaska did not become a US State until 1959.
Alaska became the 49th US state on January 3, 1959.
Alaska was admitted into the Union on January 3, 1959 becoming the 49th state to join the Union.
In 1955.
The Roman numeral IV in manganese IV sulfide indicates that manganese has a +4 oxidation state in this compound. This means that each manganese atom is contributing four electrons towards bonding with sulfur.
Alaska was admitted to the Union on January 3, 1959. It became the 49th state admitted to the Union.
The roman numeral for 4869 is (IV)DCCCLXIX. The Rules of Roman Numerals state that you cannot repeat a single numeral more than three times. So four would not be IIII. It's IV (5 - 1).
It would have been the secretary of state of Alaska
