Valence Electrons & The Periodic Table
Transcript of Valence Electrons & The Periodic Table
What's a Valence Electron??
The electrons in the outermost orbital of an atom.
Why do we care?
Valence electrons help us predict the way elements will react and what bonds will form.
The periodic table can help us find the number of valence electrons
Atoms gain or lose electrons to be happy
They want a full outer electron shell.
They will do what is easier, gain or lose.
ex. Lithium, group 1
ex. Fluorine, group 17
How many here?
because they have gained or lost electrons, atoms now have a charge.
If they gain, the charge is...
If they lose, the charge is...
Charge = Bonding Partners
Atoms with charges (ions) bond when they find partners that want to give/take the same amount.
EX. Na & Cl
Result = NaCl
Try this one..
Which groups are most/least reactive?
The closer an atom is to happiness, the more it "wants" it.
Which would be the most reactive metals?
alkali metals (1)
halogens (halides) (17)
Can you think of a group that wouldn't react at all?
Sodium in Water
Chlorine & Coca-Cola
