Uses of NO3
- The nitrate (NO3) can be used as an organic or inorganic ester or salt of nitric acid, containing the (NO3-) ion.

How many lone pairs does an oxygen atom have?
Start to mark those nine valence electrons pairs on outside atoms (oxygen atoms) as lone pairs. One oxygen atom will take three lone pairs following the octal rule (oxygen and nitrogen atoms cannot keep more than eight electrons in their valence shells). All nine valence electrons pairs (9) are spent when lone pairs are marked on oxygen atoms.
How many atoms are in a nitrate ion?
There are one nitrogen atom and three oxygen atoms in the nitrate ion. Also there is a -1 charge on the nitrate ion.
Which atom has the most chance of being the center atom?
To be the center atom, ability of having greater valance is important. Nitrogen can show valence,5. But, oxygen's maximum valence is 2. Therefore nitrogen has the more chance to be the center atom (See the figure). So, now we can build a sketch of NO 3- ion.
Does nitrogen have electrons?
No electrons pairs exist on nitrogen atom. But, on nitrogen atom, there is a +1 charge. Around the nitrogen atom, there are two single bonds and double bond.
Is there an ine valence electron pair for nitrogen?
Therefore, there is no ine valence electrons pairs to mark on nitrogen atom.
Is there a double bond between nitrogen and oxygen?
Now there is a double bond between nitrogen and one oxygen atom. There are also two single bonds (N-O) with nitrogen atom and other oxygen atoms.
What is the Lewis dot structure?
Hint : The lewis dot structure includes marking the valence electrons of every element included in the compound with the electrons used in the covalent as well as ionic bonds. For simplicity, we can use different symbols to show electrons of different elements.
How is nitrate ion formed?
Nitrate ion is formed from Hydrogen Nitrate, when the hydrogen atom leaves the compound as a positive ion , leaving its electron behind, which makes the charge on nitrate ion negative.
Why does nitrate have a negative charge?
The fact to remember here is that the nitrate ion is formed from Hydrogen Nitrate and hence, will always have a negative charge due to higher electronegativity. The negative or positive should always be included in the total counting of electrons of the compound. Here, the factors like bond length and bond angle can be ignored safely. Hence, the structure is not considered wrong if the bond angle is wrong. The important thing is to show the correct sharing of electrons.
How many valence electrons are in nitrogen?
We know there are five valence electrons in nitrogen and six valence electrons in oxygen.
What does the plus sign mean in chemistry?
Here, plus sign shows electrons of nitrogen, dot shows electrons of oxygen, and minus sign shows electron of hydrogen.
What is the nitrate in meat?
Cured meats. Nitrite consumption is primarily determined by the amount of processed meats eaten, and the concentration of nitrates in these meats. Although nitrites are the nitrogen compound chiefly used in meat curing, nitrates are used as well. Nitrates lead to the formation of nitrosamines.
What is the result of lightning strikes?
Lightning strikes in earth's nitrogen-oxygen rich atmosphere produce a mixture of oxides of nitrogen which form nitrous ions and nitrate ions which are washed from the atmosphere by rain or in occult deposition . Nitrates are produced industrially from nitric acid.
How are nitrates produced?
Nitrates are produced by a number of species of nitrifying bacteria in the natural environment using ammonia or urea as a source of nitrogen . Nitrate compounds for gunpowder were historically produced, in the absence of mineral nitrate sources, by means of various fermentation processes using urine and dung.

What is the Lewis dot structure?
Below are some rules to frame any compound’s Lewis dot structure. 1. Follow the octet rule where an atom should complete its outermost shell by the total number of 8 electrons. (Exceptions are hydrogen and boron elements)
What is the F.C of oxygen?
F.C of oxygen making single bond with the nitrogen atom. F.C = 6 – 6 – (2/2) = -1 i.e. both the oxygen atoms making a single bond with nitrogen have a negative formal charge. To calculate the total charge of the nitrate ion, a pair of +ve and –ve formal charges get canceled and there is only one –ve formal charge left on the oxygen atom.
Why is nitrate important?
It is used as fertilizers (like ammonium, sodium, potassium) in agricultural farms for higher solubility and biodegradability. It also treats heart pains. Both nitrogen and oxygen are important to an ecosystem that includes flora and fauna.
How many electrons does a nitrogen atom have?
You can convert a lone pair of one oxygen atom which already has three lone pairs to make a bond with nitrogen atom. With that, total electrons around nitrogen atom is going to be ten. It is going to break octal rule because nitrogen atom cannot keep more than eight electrons in its last shell.
How many lone pairs are there in the last shell of an oxygen atom?
That oxygen atom is connected to the nitrogen atom by a double bond has two lone pairs in its last shell. Also, there is no charge in that oxygen atom. On nitrogen atom, there are no lone pair. But there is +1 charge on nitrogen atom.
