Question

What is the formula of electronegativity? Is there any way to solve electronegativity without learning ionization energy and electron affinity?​

Answer 1

In chemistry, electronegativity is a measure of how strongly an atom attracts the electrons in a bond.[1] An atom with high electronegativity attracts electrons strongly, while an atom with low electronegativity attracts them weakly.

• Understand that chemical bonds occur when atoms share electrons. To 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 that they share a set of two electrons with each atom contributing one electron to the bond.

• 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.

• 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.
