Choose the correct response from the drop down menu  FORMDROPDOWN  that appears. Then mark your work by looking at the answers on the answer sheet. 1. Atoms contain three different particles. Protons have a (i)  FORMDROPDOWN  charge, neutrons have a (ii)  FORMDROPDOWN  charge and electrons have a (iii)  FORMDROPDOWN  charge. 2. The nucleus contains (i)  FORMDROPDOWN  and (ii)  FORMDROPDOWN . 3. What is meant by the statement: All atoms are neutral? They contain the same number of  FORMDROPDOWN  . 4. Which of the following BEST describes the term atomic number? It is the number of neutrons in the nucleus.  FORMCHECKBOX  It is the number of protons in the nucleus.  FORMCHECKBOX  It is the number of electrons in an atom.  FORMCHECKBOX  5. The mass number is the number of  FORMDROPDOWN  in the nucleus of an atom. 6. Which of the following BEST describes the term isotopes? Atoms of the same element that contain different numbers of neutrons.  FORMCHECKBOX  Atoms of the same element that contain different numbers of electrons.  FORMCHECKBOX  Atoms of the same element that contain different numbers of protons.  FORMCHECKBOX  7. Which of the following pairs are isotopes?   Answer  FORMDROPDOWN  8. The electron arrangement for the calcium atom, is  FORMDROPDOWN  9. Which of the following represent the same element (take care with this one!)? Note that represents a proton and a neutron.
