how will find electronegativity explain with an example like plzzz element nitrogen

Answer:
Hello (｡♡‿♡｡)
Explanation:
Electronegativity is the measure of how strongly an atom pulls its bonding pair of electrons towards itself. As an example, I'm going to refer back to Sal's water molecule. ... Or, you can simply say that it is how likely an atom is to gain an electron.
Hope it helps you (｡♡‿♡｡)

Answer:
In chemistry, electronegativity is a measure of how strongly an atom attracts the electrons in a bond. An atom with high electronegativity attracts electrons strongly, while an atom with low electronegativity attracts them weakly. Electronegativity values are used to predict how different atoms will behave when bonded to each other, making this an important skill in basic chemistry.
understand electronegativity, it's important first to understand what a "bond" is. Any two atoms in a molecule that are "connected" to each other on a molecular diagram are said to have a bond between them. This means essentially that they share a set of two electrons — each atom contributes one atom to the bond.
The exact reasons for why atoms share electrons and bond are a little beyond the scope of this article. If you want to learn more, try this article on the bond basics or WikiHow's own How to Study the Nature of the Chemical Bond (Chemistry).

Understand how electronegativity affects the electrons in the bond. When two atoms share a set of two electrons in a bond, they don't always share them equally. When one atom has higher electronegativity than the atom it's bonded to, it pulls the two electrons in the bond closer to itself. An atom with very high electronegativity may pull the electrons all the way to its side of the bond, barely sharing them at all with the other atom.
For example, in the molecule NaCl (sodium chloride), the chloride atom has a fairly high electronegativity and the sodium has a fairly low one. Thus, the electrons will get pulled towards the chloride and away from the sodium.
Use an electronegativity table as a reference. An electronegativity table of the elements has the elements arranged exactly like in a periodic table, except that each atom is labeled with its electronegativity. These can be found in a variety of chemical textbooks and technical articles as well as online.
Here is a link to an excellent electronegativity table. Note that this uses the Pauling electronegativity scale, which is most common. However, there are other ways to measure electronegativity, one of which will be shown below.
Remember electronegativity trends for easy estimations. If you don't have an electronegativity table handy, you can still estimate an atom's electronegativity based on where it is located on a normal periodic table. As a general rule:
