Why do Venus Flytraps need to eat insects?
They need the nitrogen from their corpses.

How was Thompson's model of the atom ultimately incorrect?
He envisioned the electrons just mixed into the atom, when in reality the circle around it.

This odd family only has a few naturally occurring elements, but most are synthesized in labs.

Raccoon.

Describe how Rutherford's Gold Foil Experiment proved the existence of the nucleus
When the alpha particles flew back at weird angles, they had struck something solid in the middle, instead of passing through the emptiness between.

Why did it take so long for people to believe in atoms?
They are essentially invisible.

Why don't Noble Gases form bonds with other elements?
They have a stable valence shell, filled with 8 electrons.

How would you find the valence number for a metalloid?
Check the charge number in the upper right corner; if it is negative, use the family number; if it is positive, use that.
