What is a monatomic ion has an oxidation number?
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.
How does the oxidation number of a monatomic ion compare to its 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.
What is The charge of a monatomic ion called?
Oxidation Number
Is the charge of a monatomic ion its oxidation number?
Yes. it is
With monatomic species what does the oxidation number indicate?
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.
What is the oxidation number of a monatomic ion equal to?
In most cases it is the value of its charge, but not always.
What are the rules to assign oxidation numbers?
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.
The charge of a monatomic ion is equal to the atom's?
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.
What is the oxidation number of each ion in the compound MgBr2?
In MgBr2, the magnesium ion (Mg) has an oxidation number of +2, while the bromide ion (Br) has an oxidation number of -1.
What is the oxidation number of CO3?
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.
What is the oxidation number of nitrito?
The oxidation number of the nitrite ion (NO2-) is -1. The oxidation number of nitrogen in the nitrite ion is +3, and each oxygen atom has an oxidation number of -2.
What is the oxidation number of the molecular ion ammonium NH4 in ammonium chloride NH4Cl?
The oxidation number of nitrogen in the ammonium ion NH4+ is -3, and the oxidation number of hydrogen is +1. In ammonium chloride NH4Cl, the net charge on NH4 is +1 because the chloride ion Cl- has an oxidation number of -1.
