(a)  

How are atoms identified?

• Atoms are identified by their mass number.
• Atoms are identified by their color.
• Atoms are identified by their atomic number. (aka number)

• Atoms are identified by their shape.

What is the atomic weight of an atom?

• Number of Protons

• Number of Protons, Neutrons, and electrons

• Number of Protons and Neutrons

What is radioactive? (Like radium) What happens to the atom? What is it called?

What does the radium nucleus give off when artificial transmutation happened?

• Beta Particle

• Alpha Particle

• Gamma Particle

In nuclear fission reactions powerful rays are given off similar to x-rays, but also neutrons which bombard other atoms causing a what?

• nuclear fusion
• thermal explosion
• radioactive decay
• chain reaction
