Electron Affinity vs:

Electron Affinity vs Ionization Energies vs Electronegativity By: Sharlene Lim, Tim Stone, & Nicholas Lukban

Electron Affinity:

Electron Affinity Definition : the energy change when an electron is added to a neutral atom and becomes negative In simpler terms, the process of adding an electron.

Electron Affinity:

Electron Affinity -On a periodic table, affinity rises traveling left and rises going up -Depending on where the element is on the table determines how easily it can gain electrons -The closer to the right it is, the easier it can gain electrons (not including Group 18) Opposite of Ionization Energy This process is usually confined to elements in Group 6 and 7. This process can also help with stabilizing valence electrons and bonding two atoms.

Electron Affinity:

Electron Affinity JJ Thomson discovered electrons, which directly affects electron affinity and its increase.

Ionization Energies:

Ionization Energies Definition: the energy change when an electron is removed from a neutral atom and becomes positive Energy is measured in kilojoules per mole (kJ/ mol ) In simpler terms, the process of removing an electron.

Ionization Energies:

Ionization Energies Opposite of Electron Affinity -On a periodic table, ionization energy rises up as it goes left and as it goes up. -Group 1 metals have the lowest ionization energy -They lose electrons easily -Noble gases have highest ionization energy -They don’t lose electrons easily

Ionization Energies:

Ionization Energies Generally, nonmetals have higher ionization energies than metals because nonmetals have fuller valence electrons. This process can help with stabilizing valence electrons and bonding two atoms.

Ionization Energies:

Ionization Energies Mendeleev arranged one of the first periodic tables partially by ionization energy

Electronegativity:

Electronegativity Definition: the measure of the ability of an atom in a compound to attract electrons from another atom In simpler terms, it measures the attraction between two atoms by it’s electrons.

Electronegativity:

Electronegativity -Affected by atomic number and distance of valence electrons Fluorine is the most electronegative element, while caesium and francium is the least. -On the periodic table, generally, electronegativity tends to increase across each column. -The number is known as the Pauling units These values go from highest to lowest from 4.0 to 0.7

Electronegativity:

Electronegativity Robert Sanderson Mulliken made a new scale for measuring electronegativity by using electron affinity. Linus Pauling introduced the concept of electronegativity in 1932 and established the Pauling scale by using numerous properties of molecules. There were many scientists that created their own electronegativity scale such as Allred- Rochow , Sanderson, and Allen using different relationships and properties.
