what is electro negetivity?

Answer 1

1.The ability of an atom to inductively pull electrons towards itself. The more electronegative an atom, the tighter it pulls the electrons. Commonly measured on the Pauling scale, the higher the electronegativity, the more strongly an atom attracts electrons. Note electronegativity is a characteristic property of a given atom.

2.A measurement of how much an atom tends to steal electrons from atoms that it's bonded to. Elements at the top right of the periodic table (excluding the noble gases) are very electronegative while atoms in the bottom left are not very electronegative (aka "electropositive")

3.the tendency of an atom to attract electrons; the most common quantitative scale was developed by Linus Pauling (1901 - 1994), one of only four people to win two Nobel prizes [Can you name the other three? Hint: one was a Polish woman.]

(The reverse of electronegativity, the ability of an atom to lose electrons, is known as electropositivity.)

Answer 2

Electronegativity is defined as the ability of an atom to withdraw electron density from a covalent bond between it and another atom. The covalent bond consists of a shared pair of electrons.

Electronegativity as a concept had been around for a while, until one day a scientist called Linus Pauling analysed some characteristics of the elements and the compounds they formed. He figured out a way to calculate a value to represent each element's electronegativity. This number indicates how strongly the atom withdraws electron density from a covalent bond, elements with high electronegativity values withdraw more electron density from a covalent bond, elements with low electronegativity values withdraw little electron density from a covalent bond. Fluorine is the most electronegative element, Francium is the least electronegative. Below is a periodic table of electronegativities.

Answer 3

It's the property of an atom to receive extra electrons to complete its octet (8 electrons on an orbital ) becoming a negative ion .
Oxygen and other non-metals are electronegative ,metals are electropositive

Answer 4

It is the property of an atom to become negatively charged ion or anion or simply put, to accept electrons. Generally non-metals show this property, i.e. they are electronegative. For eg. Chlorine, Oxygen, etc are electronegative.

Answer 5

the ability of an atom to withdraw electron density from a covalent bond between it and another atom. The covalent bond consists of a shared pair of electrons

Answer 6

the ability of an atom to withdraw electron density from a covalent bond between it and another atom. The covalent bond consists of a shared pair of electrons.

Answer 7

Electronegativity is relative tendency to gain electron and become electronegative species (-). For eg. chlorine has more tendency to gain electron and sodium has more tendency to lose electron . Hence chlorine is greater electronegative than sodium.Electonegativity is relative term and has no unit .
