  1. 1In the current nuclear model, the atoms contain three types of particles?
    1. AVerdadeiro
    2. BFalso
  2. 2Electrons?
    1. Anegatively charged
    2. Bpositively charged
    3. Cneutral- no charge
  3. 3Protons?
    1. Anegatively charged
    2. Bpositively charged
    3. Cneutral- no charge
  4. 4Neutrons?
    1. Anegatively charged
    2. Bpositively charged
    3. Cneutral- no charge
  5. 5Label the current nuclear model.Imagem da pergunta 5
    1. AElectron
    2. BProton
    3. CNeutron
    4. DElectron
    5. EProton
    6. FNeutron
    7. GElectron
    8. HProton
    9. INeutron
  6. 6Tick all the statements that are true about isotopes.
    1. ADifferent forms of the same element.
    2. BIsotopes have atoms with the same number of protons and neutrons.
    3. CThey have the same atomic number (and so the same charge on nucleus) , but different mass numbers.
    4. DAll elements have isotopes, but there are usually one or two stable ones.
    5. EThe unstable isotopes are not radioactive so they can not decay into other elements and give out radiation.
  7. 7Tick the correct definition for radioactivity.
    1. ARadioactivity is all to do with things randomly giving out radiation. Some radiation is ionising , which means it can knock electrons off atoms to create ions.
    2. BRadioactivity is to do with the radiators in your house giving off magnesium signals
    3. CRadioactivity is about things specifically giving off radiation and it can not create ions.
  8. 8Alpha particles are released by high mass, proton rich unstable nuclei. [blank_start]The alpha particle is a helium nucleus[blank_end]; it consists of two protons and two neutrons. It contains no electrons to balance the two positively charged protons. Alpha particles are therefore positively charged particles moving at high speeds.
    1. AThe alpha particle is a helium nucleus
    2. BThe alpharetine particle is oxygen based
    3. CThe alpha particle is negatively charged
  9. 9Beta particles are emitted by neutron rich unstable nuclei. [blank_start]Beta particles are high energy electrons[blank_end]. These electrons are not electrons from the electron shells around the nucleus, but are generated when a neutron in the nucleus splits to form a proton and an accompanying electron. Beta particles are negatively charged.
    1. ABeta particles are high energy electrons
    2. BBetalium particles are helium
    3. CBeta particles are positively charged
  10. 10[blank_start]Gamma rays are electromagnetic[blank_end] waves of very short wavelength and high frequency. Gamma rays are emitted by most radioactive sources along with alpha or beta particles. After alpha or beta emission the remaining nucleus may still be in an excited energy state. By releasing a gamma photon it reduces to a lower energy state. Gamma rays have no electrical charge associated with them.
    1. AGamma rays are electromagnetic
    2. BGammalium rays are radioactive
    3. CGamma rays are positively charged
