∙ 9y agoYes, because the anion sodide (Na-) is known.
Oxidation number of sodium is +1 so I dont thik there is such compound exist

How does the oxidation state of a transition metal determined from chemical formula?
A pure metal has the oxidation state zero.
When is the oxidation state of metal indicated in the name of a compound?
It is a method to distinguish different ions of a metal.
When Is the oxidation state of metal indicated in the name of the compound?
It is a method to distinguish different ions of a metal.
When is the oxidation state of a metal indicated in the name of a compuond?
The oxidation state of a metal is indicated in the name of a compound if and when that metal has more than one oxidation states. The oxidation state is then indicated by a Roman numeral placed in parenthesis next to the metal (Stock System).
Is there any compound of manganese in negative oxidation state and if exist then formulae?
no, it does not exist
When is the oxidation state of a metal indicated in the name of a compound?
When the metal can exist in more than one oxidation state

What is the correct name for compound Cr2O3?
For ionic compounds such as the one mentioned above, naming them is relatively easy. As we all know, an ionic compound consists of a metal ion(which is usually positive) and a negative ion. Hence, the names for metallic compounds are always in the following format: Name of metal + Name of negative ion However, do take note that for transition metals, the oxidation state has to be included. This is because transition metals have multiple oxidation states. The oxidation state of the metal is presented by: Metal (oxidation number). For example, rust is Iron (III) oxide. Cr2O3 is hence named chromium (III) oxide.
When is H in negative oxidation state?
When it has gained one electron, forming Hydride ions
