Ernest Rutherford discovered that atoms were mostly _________________. 

• negatively charged
• positively charged
• electrons
• empty space. 

This was the first model of the atom ever proposed. It was simple and described atoms as tiny spheres that could not be broken down into smaller pieces.

• Democritus's model of the atom
• The "Plum Pudding Model" of the atom
• The "Rutherford Model" of the atom
• The "Quantum Mechanical Model" of the atom
