In most cases it is the value of its charge, but not always.
A monatomic ion is an ion consisting of a single atom with a positive or negative charge. The oxidation number of a monatomic ion is equal to the charge of the ion.
It is equal to the charge. Oxidation number depends on charge.
The oxidation number of a monatomic ion equals its charge. For example, the oxidation number of a sodium ion (Na+) is +1, which matches its charge of +1.
The charge. Cations and anions have an oxidation number equal to their charge, for example in Fe2+, Fe hasan oxidation number of +2 and in S2- S has an oxidation number of -2. Uncharged atoms have zero oxidation number.
Oxidation Number
Yes. it is
In a pure element, the oxidation number is zero. In a monatomic ion, the oxidation number is equal to the charge of the ion. Oxygen is typically assigned an oxidation number of -2, unless in a peroxide where it is -1. Hydrogen is typically assigned an oxidation number of +1 when bonded to nonmetals and -1 when bonded to metals. The sum of the oxidation numbers in a neutral compound is zero, and in a polyatomic ion it is equal to the charge of the ion.
This is because a monatomic ion forms when an atom gains or loses electrons to achieve a stable electronic configuration. The charge of the ion is determined by the number of electrons gained or lost, and is equal to the atom's group number in the periodic table for main group elements.
The oxidation number of carbonate ion (CO3) is -2. Each oxygen atom has an oxidation number of -2, and the sum of the oxidation numbers in the ion must equal the charge of the ion, which is -2.
Yes, the oxidation number of an ion is equal to the number of valence electrons the ion contains. Valence electrons are the electrons in the outermost shell of an atom, and they are involved in forming chemical bonds, which also determines the oxidation state of an ion.
A metal and a nonmetal would form an ionic bond. In an ionic compound, a metal ion would have a positive oxidation number equal to its ionic charge. A nonmetal would have a negative oxidation number equal to its ionic charge.Examples:NaCl oxidation numbers: sodium has an oxidation number of +1, chloride has an oxidation number of -1. So the overall charge of NaCl is zero.CaCl2 oxidation numbers: calcium has an oxidation number of +2, the chloride ion has an oxidation of -1. Since there are two chloride ions, the total negative oxidation number is -2, so CaCl2 has an overall charge of zero.
It must be equal to the charge on the compound/ion
