Ionization Energy vs. Electronegativity

Postby Eileen Si 1G » Sun Nov 10, 2019 3:29 am

What is the difference between ionization energy and electronegativity? If so, is there a way to differentiate between the two just by looking at the periodic table?

Ionization energy is minimum amount of energy needed to remove an electron from a neutral atom. Electronegativity is a measure of an atom's tendency to attract a pair of electrons.

Both ionization energy and electronegativity generally increase as you go left to right on the periodic table and as you go up the periodic table.

Think of ionization energy as what it takes to make an anion and electronegativity is how badly it wants to be negative. That's how I remember it. Don't know if that helps

Also, electronegativity refers to the ability of an atom in a molecule to attract shared electrons. Ionization energy does not refer to molecules, only unbonded atoms.

Both ionization energy and electronegativity increase toward the upper right hand side of the periodic table.

Ionization energy is the amount of energy it takes to remove an electron from an atom while electronegativity is the atom's ability to attract an electron.

Both have similar periodic table trends, increasing as you move to the top right corner.

Ionization energy has the same trend as electronegativity on the periodic table.

Ionization energy is the amount of energy required to remove an electron. Electronegativity is the likelihood that an atom will gain an electron.

Ionization Energy and Electronegativity are the inverse of each other. Electronegativity is an atom's tendency to attract an electron. In contrast, the ionization energy is the energy needed to remove an electron from an atom. Since having more tendency to attract an electron means that the atom has less tendency to give an electron, more electronegative atoms require more energy to ionize. Both ionization energy and electronegativity increase as you go up and towards the right of the periodic table
