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.


Here is an image summing all of the trends into one:




Here is a website elaborating on the trends: https://www.khanacademy.org/science/chemistry/periodic-table/periodic-table-trends-bonding/v/atomic-radius-trend

  1. Thanks Kendall for this great post! I liked how you defined what each trend means, and with pictures showed how those were put in place. I also enjoyed how you provided a link to this topic to help further understand and elaborate on the topic. Thanks again!
