Two main-group elements are highlighted in the outline of the Periodic Table below: Y What can you say about these elements without knowing exactly which they are? Use that knowledge to answer the questions in the following table, if possible. Important: do not try to figure out exactly which elements are marked, and then use your knowledge of the properties of each specific element. You don't need to. You will also be marked wrong for any answer, correct or not, that can't be determined from the rough location of each marked element in the Periodic Table. The atoms of which element are more likely to be the cations in an ionic O Element X O Element Y X

1. Examine the statement “No two elements have the same line spectrum.” Explain why this can be used like a fingerprint to identify a substance.
Which of the following statements is correct about the periodic law? * Properties of elements are periodic function of their atomic mass. The physical and chemical O properties of elements are periodic function of their atomic number. The physical properties of elements O are periodic function of their atomic weight. The chemical properties of O elements are periodic function of their atomic number ! This is a required question Which best describe the Rutherford's gold foil experiment? * Negative and positive charges are spread evenly throughout the atom. Alpha particles have a positive charge. Gold is not a dense as previously thought There is a dense positively charged nucleus at the center of an atom.
MEASUREMENT AND MATTER Organization of the Periodic Table Read each description in the first column of the table below. If any chemical element with atomic number of 92 or less matches the description, check Yes and enter the chemical symbol of an element that matches. Otherwise check No in the second column. description An element in Period 1 and Group 8A. A metalloid in Group 4A. An alkali metal with a lower atomic number than nitrogen. A main-group element in Period 6. Does any element with Z≤ 92 match the description? Yes Yes Yes Yes No No O No No If you checked yes, give the symbol of an element with Z ≤ 92 that matches.

The isotope carbon11 does not occur in nature but has been made in the laboratory. This isotope is used in a medical imaging technique called positron emission tomography (PET, see Section 9.7A). Give the number of protons, neutrons, and electrons in an atom of carbon11.
16. Rutherford's experiment with gold estimated the radius of a gold atom to be approximately 1 x 10⁹ cm. Suppose the radius of the nucleus is the same as a basketball. Would the volume of the atom be bigger or smaller than that of a typical domed athletic stadium? Show a little math to support your answer.
