  • Q1
    A researcher wants to experiment with an element that reacts like phosphorus (P) but has a greater atomic mass. Which element should the researcher select for the experiment?
    Silicon (Si)
    Arsenic (As)
    Sulfur (S)
    Nitrogen (N)
  • Q2
    The model of the periodic table below shows the locations of four elements. A student is asked to identify an element that is a pale-yellow brittle solid and does not conduct electricity. At which location in this periodic table would the element most likely be found?

  • Q6
    Which pair of properties describes the elements in Group 18?
    They are gaseous at room temperature and chemically stable.
    They are magnetic and boil at low temperatures.
    They have eight valence electrons and are flammable.
    They are chemically stable and liquid at room temperature.
  • Q7
    A student is studying the ways different elements are similar to one another. Diagrams of atoms from four different elements are shown below. Which two atoms are of elements in the same group in the periodic table?
    Question Image
    Atom 2 and Atom 3
    Atom 1 and Atom 2
    Atom 3 and Atom 4
    Atom 1 and Atom 4
  • Q8
    Element R and Element Q have the same number of valence electrons. These elements both have similar chemical behavior, but Element R has fewer energy levels than Element Q. Which statement best describes the positions of the two elements in the periodic table?
    Question Image
    The two elements are in the same period, with Element R the first element in the period and Element Q the last element.
    The two elements are side by side in the same period, with Element Q to the left of Element R
    The two elements are in the same group, with Element R just above Element Q.
    The two elements are in the same group, with Element Q at the top of the group and Element R at the bottom.
  • Q9
    Students in a science class prepared flash cards so that they could quiz one another about the arrangement of the periodic table. One of the flash cards contained information about two elements, Element L and Element M. The students had to use the information on the flash card to determine possible positions of the two elements on a blank periodic table. Which periodic table has the elements placed in locations that match the information on the flash card?
