- Q1A 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)60s8.5c
- Q2The 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?234160s8.5c
- Q3The periodic table is organized into groups and periods of elements. The characteristics of a certain group of elements are listed below. Which of these elements is in this group?AluminumStrontiumSiliconLithium60s8.5c
- Q4Which two elements on the periodic table are in the same period?K and BaF and ClSe and TeSn and Rb60s8.5c
- Q5Students were asked to identify the location of elements in the periodic table based on clues printed on game cards. Based on the data, which periodic table shows the correct location of the four elements?#texas/ebf4b61e-8fbe-4c0b-9c17-489e5d067b7d/A.png#texas/ebf4b61e-8fbe-4c0b-9c17-489e5d067b7d/C.png#texas/ebf4b61e-8fbe-4c0b-9c17-489e5d067b7d/B.png#texas/ebf4b61e-8fbe-4c0b-9c17-489e5d067b7d/D.png60s8.5c
- Q6Which 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.60s8.5c
- Q7A 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?Atom 2 and Atom 3Atom 1 and Atom 2Atom 3 and Atom 4Atom 1 and Atom 460s8.5c
- Q8Element 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?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 RThe 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.60s8.5c
- Q9Students 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?#texas/200e4bac-1e14-4782-9f23-c7f6fbfdd056/D.png#texas/200e4bac-1e14-4782-9f23-c7f6fbfdd056/B.png#texas/200e4bac-1e14-4782-9f23-c7f6fbfdd056/C.png#texas/200e4bac-1e14-4782-9f23-c7f6fbfdd056/A.png60s8.5c
