The Concept of Electronegativity
This time, we will discuss one of the chemical terms that often confuses novice chemists. Electronegativity. Electronegativity is the ability, or tendency of an atom, to attract shared-pair electrons towards itself.

00:00Hi everyone, thank you for being an active viewer of this channel.
00:08This time, we will discuss one of the chemical terms that often confuses novice chemists.
00:14Electronegativity.
00:17Let's read a simple definition of electronegativity.
00:21Electronegativity is the ability, or tendency of an atom, to attract shared pair electrons
00:26towards itself.
00:29Maybe you have a different definition, that's not a problem.
00:36To understand this definition, consider the following illustration.
00:42These are atoms 1 and atom 2.
00:47Let's say atom 1 has one unpaired electron in the outermost shell.
00:53Atom 2 also has one unpaired electron in the outermost shell.
01:01Both atoms are unstable.
01:04To achieve stability, the two electrons must form a pair.
01:10This is what is meant by a shared pair electrons.
01:16Because it connects two atoms, the shared pair electrons forms a chemical bond.
01:22So what does it have to do with electronegativity?
01:27Even though it is in the form of a molecule, its atomic properties still exist.
01:32The atomic nucleus of each atom can affect chemical bonds.
01:38The shared pair electrons can be right in the middle of the atom.
01:44The shared pair electrons may tend to be closer to the nucleus of atom 1.
01:50Or the shared pair electrons may also tend to be closer to the nucleus of atom 2.
01:55Well, this is the role of the electronegativity value of the atom.
02:02The electronegativity value can determine the tendency of the nucleus of an atom to
02:06attract shared pair electrons towards itself.
02:10We will study this in more detail in the next video.
02:15Hopefully, there are some benefits in the video.
02:19Happy learning everyone!
