1. atomic and subatomic particles
Determine if statements about the seven subatomic particles (p+, e-, n0, α particles, β particles, γ rays) are true or false!

2. recap what we know
With your partner you have one min to list as many things as you can about each of the following!
electrons
protons
neutrons 

3. recap what we know Ions atoms that have gained or lost Cations (+)
Anions (-) 

4. new particles α (alpha) particles β (beta) particles γ (gamma) rays
video introduction- take note of facts on each type of particle

5. α (alpha), β (beta), and γ (gamma) particles
He atom stripped of electrons
2 protons + 2 neutrons
Deflected toward the negative charge (have a positive charge)

6. α (alpha), β (beta), and γ (gamma) particles
High speed electrons
Small mass
Deflected toward the positive charge (have a negative charge)

7. α (alpha), β (beta), and γ (gamma) particles
Photons (light/radiation)
No mass
NOT deflected by a magnetic field (no charge)

8. True/false
On a half sheet: You have five minutes to develop 4 GREAT t/f questions that you will give to another group for practice If you finish early refine, double check, and/or make better t/f questions

9. True/false “check” correct false statements
A proton and electron have equal masses.
Alpha particles are positively charged
Beta particles are larger than alpha particles
Gamma rays do not have charge or mass
Beta particles are composed of 2 protons and 2 neutrons
Gamma rays are bent in a magnetic field
Beta particles are high speed electrons
All of the following are positively charged: protons, alpha particles, and anions
Neutrons are much larger than electrons and beta particles
Beta particles are bent toward a positive charge
