Why do noble gases have zero oxidation numbers?
Oxidation state of an element is directly or indirectly related to the no. of its valence electrons or the no. of valencies in its Valence shell.In case of noble gases,their outermost shell is completely filled so no vacancy is available in the outer most shell. Thus the oxidation state is zero(0) for Noble gases.
Why is the oxidation number 0?
By definition, the oxidation number of an atom is the charge that atom would have if the compound was composed of ions. 1. The oxidation number of an atom is zero in a neutral substance that contains atoms of only one element. Thus, the atoms in O2, O3, P4, S8, and aluminum metal all have an oxidation number of 0.
What is the oxidation number of the noble gases *?

| The oxidation number of the group that includes oxygen and sulfur is _____., | -2, |
| The most common oxidation number of the group that includes carbon and silicon is _____., | +4 or -4, |
Why do nonmetals have a negative oxidation number?
Nonmetals gain one or more valence electrons to become stable, giving them a negative oxidation number. Atoms want to have full outer shells of electrons. When they gain negative electron(s), they acquire an overall negative charge.
Can oxidation no be zero?
a) The net charge on neutral atoms or molecules is zero. So the overall oxidation state of them is zero. For example oxidation state of elemental atoms such as sodium, magnesium, iron is zero.
Can oxidation number be zero illustrate?
The oxidation number could be positive, negative, or zero, and it indicates if electrons are lost or gained. If the oxidation number is positive, then this means that the atom loses electrons, and if it is negative, it means the atom gains electrons. If it is zero, then the atom neither gains nor loses electrons.
Are noble gases reactive?
Because they’re reluctant to share electrons from their filled outer electron shells, noble gases are generally considered unreactive.
Why do nonmetals have both positive and negative oxidation numbers?
If a non metal combines with a non metal with a higher electro negativity than the no n metal then the non metal with have a positive charge. that is the electrons will be pulled closer to the Oxygen causing Oxygen to have a negative charge and the Sulfur to have a positive charge.
What is the oxidation number of nonmetals?
+1
In ionic compounds, the ionic charge of an atom is its oxidation number. The sum of the oxidation numbers of all the atoms in an ion or molecule is equal to its net charge. In compounds with nonmetals, the oxidation number of hydrogen is +1.
What is the oxidation No of No?
+2
Answer: The oxidation number of nitrogen is +2.
