Essential Questions:
How do valence electrons determine
an atom’s chemical properties,
including reactivity?
Let’s watch a video 
https://www.youtube.com/watch?v=V

Bell Work
1. What is atomic mass?
2. Between K and Li which one is
heavier?
3. What do they have in common?

Remember?
Valance Electron
• An electron in the outer shell
of an atom that can
participate in forming
chemical bonds with other
atoms.
• The number of valance
electrons determines the
element’s reactivity.

Periodic Table and Reactivity
Groups on the Periodic Table
• The groups or families on
the PT are the columns
numbered from 1-18.
• Same number of
valance electrons (the
electron on the very last
shell).
• Chemical properties are
very similar.
• Groups 1 is the most
reactive and group 18 is
the most inert (stable).

Periodic Table and Reactivity
Reactivity of atoms
• The ability of atoms to
combine or separate with
other atoms to create new
substances (chemical
reaction)
• Valance electrons are the key
to this process.
• Reactivity changes across the
periodic table.
