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!

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 

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

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

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)

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

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

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

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 TRUE! FALSE! TRUE! FALSE! FALSE! TRUE! FALSE! TRUE! TRUE!

Practice! Write long short AND orbital filling for the following! Co   Se2- Rb1+
