Most of the time the oxidation number of the nonmetals are?
Negative (such as -2 in compounds like O2 or Cl-) or positive (such as +3 in compounds like NCl3), depending on the element and the compounds involved.
How do you find a oxidation number?
Finding the oxidation number of an atom often requires you to use certain atoms as references. Oxygen and hydrogen are the most common examples. Almost all the time, hydrogen has an oxidation number of +1, and oxygen -2. The sum of all oxidation numbers is equal to the charge on a given chemical species. Therefore, you can use these known oxidation numbers and the charge to deduce the other oxidation numbers. Take chromate for example. Chromate has the chemical formula CrO42-. The charge on this species is -2. There are four oxygen atoms, each with an oxidation number of -2. Therefore, their combined effect is -8. The chromium atom must have an oxidation number that, when added to -8, will give the charge on the ion, -2. Therefore, chromium has an oxidation number of +6 in this case. A similar approach can be used on a wide variety of molecules and ions.
What is the oxidation number of iron oxide?
As a transition metal , iron exhibits several oxidation numbers. As FeO (Ferrous Oxide) its oxidation no,. is ;2; usuallu written as 'Iron(II)Oxide'. This is pale green in colour As F2O3(Ferric Oxide) its oxidation No. is '3' usually written as Iron(III)Oxide. This in (Rust) Brown/Red in colour. Gives human blood its red colour. NB Note the Roman Numerals to indicate oxidation state. NNB Iron has six(6) electrons in its outer(valence) 'd' electron shell. The oxidation numbers indicates that only '2' or '3' as the case may be, electrons are involved in combining with another atom. The other electrons remain uncombined.
What is the oxidation number for P in Na3PO3?
Well, isn't that a happy little question! In Na3PO3, the oxidation number for Na is +1 and for O is -2. Since the overall charge of Na3PO3 is neutral, we can calculate the oxidation number for P to be +3. Just remember, there are no mistakes in oxidation numbers, only happy little accidents!
How do you use the word oxidation in a sentence?
Oxidation is a word used to describe something that is going through the process of being oxidized. A good sentence is, while coal is burning any sulfur goes through the oxidation process and turns into sulfur dioxide.
Most of the time the oxidation number of the nonmetals are?
Negative (such as -2 in compounds like O2 or Cl-) or positive (such as +3 in compounds like NCl3), depending on the element and the compounds involved.
What time describes the most reactive nonmetals that have seven valence electrons?
Halogens

Do nonmetals have energy?
Usually (all the time as far as we're concerned.
Why aren't non metals strong?
We cannot determine if nonmetals are strong or not since they exist in any of the 3 states:solid,liquid,or gases. But generally,nonmetals are characterized that they are non-ductile. There are some nonmetals that are strong such as:wood and glass,and in the same time there are some nonmetals that are not as strong such as :coal which we can dismantle easily.
Is the product of two positive numbers greater than the sum of the two numbers?
Not always, but most of the time.
What time of day are most winning lottery numbers sold?
Daytime
When are rational numbers not natural?
Most of the time. For example, when they are negative integers.

What occurs when some materials are exposed to oxygen and water over time and can result in rusting?
Oxidation happens.
Why nitrophenol cannot be prepared by oxidation of cumene?
Most obviously because there's no nitrogen in it; you're going to have a hard time making NITROphenol without nitrogen.
Why is rusting a kind of slow oxidation?
as it takes a lot of time
