Periodic Trends

In class we had a lecture over all of the different periodic trends. The majority of the trends, we have learned, run up and to the left. There are four major trends: electron affinity, electronegativity, atomic radius, and ionization energy.

Electron Affinity: It is known to be the ease at which an electron may be added to an atom.

Electronegativity: It is the tendency of an atom to draw electrons toward itself when chemically combined with another element.

Atomic Radius: The size of the atom's radius.

Ionization Energy: It is the energy needed to remove an electron from a gaseous atom.
