Periodic Properties and Periodic Properties and TrendsTrendsAtomic Radius:

-Size of an atom.

-The distance from the nucleus to the outermost energy level in picometers, pm. (1pm = 1x10-12 m)

Ionization Energy:-The amount of energy needed to remove a valence electron

from an atom. -The amount of energy needed to overcome the attractive

force the ve- has with protons in the nucleus. -Energy required for an atom to become a cation, more

stable. Electronegativity: -The degree of attraction one atom’s protons has toward

another atom’s ve-.-Determines the type of bond between the atoms, ionic or

covalent.

History of the Periodic TableHistory of the Periodic Table Dmitri Mendeleev: • Russian chemist and teacher

•When organized elements into groups by similar chemical properties, he observed the periods increasing in atomic mass. (1869)

• His organization system was successful at predicting undiscovered elements.

•Do you observe any inconsistencies with his organization system?

History of Periodic TableHistory of Periodic TableHenry Moseley:

•British Physicists

•Tweaked Mendeleev’s periodic table.

•When elements were placed in groups by chemical properties, the periods consistently increased by atomic number. (1913)

•Current organization of elements on the periodic table.
