Answers will vary, but should include facts including that

valence electrons are the electrons in the outermost

shell of an atom and are the ones that can enter into a

reaction with other atoms. For most atoms, the magic

number is 8 electrons to make a compound stable.

Elements in Group 1 have 1 valence electron and are

most reactive. Elements in Group 18 have 8 valence

electrons, making them “full” or “happy” and not

observed

or

measured

without

changing the composition of matter.

• Used to observe and describe matter.
