Match the following valance electron trends to their correct response.

• 8 valence electrons

• Gain them

• 4 valence electrons

• Lose or Gain

• More valence electrons (5-7)

• Lose them

• Few valance electrons (1-3)

• Keep them

For some elements in groups, how can we determine the number of valence electrons they have just by looking at the periodic table?

• Not possible

• I have no clue

• No consistent way

• The group number they reside in

Match the method of determining valence electrons with the result

• Group 1

• Look up

• Helium

• Drop the 1

• Groups 3-12, Lanthanides/Actinides

• 2 valence!

• Groups 13-18

• 1 valence electron

• Group 2

• 2 valence electrons
