The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The correct answer is: In nature, there are more sulfur-34 than sulfur-32 isotopes.<\/em><\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

Sulfur has two main stable isotopes: sulfur-32 (\u00b3\u00b2S) and sulfur-34 (\u00b3\u2074S). The atomic mass of sulfur listed on the periodic table (32.066 amu) represents the weighted average of the masses of these isotopes, based on their relative abundance in nature.<\/p>\n\n\n\n

    \n
  1. Some sulfur atoms contain 18 neutrons<\/strong>:
    This statement is true<\/em>. Sulfur-32 has 16 protons (because sulfur’s atomic number is 16), and since the mass number of sulfur-32 is 32, the number of neutrons is 32 – 16 = 16 neutrons. Sulfur-34 has 34 – 16 = 18 neutrons. Therefore, some sulfur atoms (those that are sulfur-34) contain 18 neutrons.<\/li>\n\n\n\n
  2. On average, the mass of a sulfur atom is 32.066 amu<\/strong>:
    This statement is true<\/em>. The atomic mass listed on the periodic table is a weighted average of the masses of sulfur’s isotopes, which reflects the relative abundance of each isotope. The average mass, 32.066 amu, is influenced by the higher abundance of sulfur-32 relative to sulfur-34.<\/li>\n\n\n\n
  3. Some sulfur atoms weigh 32 amu<\/strong>:
    This statement is true<\/em>. Sulfur-32 has an atomic mass of exactly 32 amu. Since sulfur-32 is the most abundant isotope of sulfur, a significant fraction of sulfur atoms will weigh 32 amu.<\/li>\n\n\n\n
  4. In nature, there are more sulfur-34 than sulfur-32 isotopes<\/strong>:
    This statement is false<\/em>. In nature, sulfur-32 is much more abundant than sulfur-34. Approximately 95% of sulfur atoms are sulfur-32, while only about 4.2% are sulfur-34. This difference in abundance is why the atomic mass of sulfur is closer to 32 amu than to 34 amu.<\/li>\n<\/ol>\n\n\n\n

    Thus, the false statement is the one that claims there are more sulfur-34 isotopes than sulfur-32 in nature.<\/p>\n\n\n\n
