Multiple Choice

Which element is depicted from this orbital diagram

• Fluorine
• Neon
• Chlorine
• Argon

• ​2D Illustration of an element

• The Bohr Model shows the number of electrons per energy level. It does not show sublevels, but it can help identify valence electrons.

Bohr's Model

• Noble gasses are the last column of the periodic table

• They are less reactive than any other atoms on the periodic table because their final orbital is filled

Noble Gases

• Shortcut (use the last noble gas)

Noble Gas Configuration

​Core Electrons – go up one energy level and over to the noble gas

Periodic Groups

Groups go UP AND DOWN. There are 18 groups in total on the periodic table. Groups have names known as families

• Valence electrons are electrons in the outer energy level.

• ONLY s & p orbitals are valence electrons!

Valence electrons

What do group numbers tell us?

Each group number tells us the number of valence electrons, which tells us the Lewis Dot Structure of an atom
