The eighth element, starting from a given one, is a kind of repetition of the first, like the eighth note of an octave in music. -John Alexander Newlands, 1865

The Periodic Table

Unit Essential Question:

How are the properties of element related to arrangement in the periodic table?

Image from theperiodictable.com

The periodic table displays information in squares. They always have the symbol for the element and the atomic number. Almost all have the average atomic mass. Other information can include: the name, the valance structure, density, state at room temperature, boiling point, melting point, electronegativity, ionization energy, and atomic size.

Filling Orbitals

The periodic table can help figure the electron configuration of an element.• Each row corresponds to

the principal energy level, the d-orbitals are one less, and the f-orbitals 2 less.

• The location of an elements corresponds to the orbitals being filled.
