Let's embark on this journey to unravel the mysteries of sulfur isotopes and atomic structure.

Decoding Atomic Symbols The Building Blocks of Chemistry

To accurately determine the symbol for a sulfur particle with 18 neutrons and 18 electrons, we must first understand the basic components of an atom and how they are represented in atomic symbols. An atom consists of three primary particles protons, neutrons, and electrons. The number of protons defines the element; for example, all sulfur atoms have 16 protons. This number is known as the atomic number and is represented by the symbol Z. Neutrons, along with protons, reside in the nucleus of the atom and contribute to its mass. The sum of protons and neutrons is the mass number, denoted by A. Electrons orbit the nucleus and, in a neutral atom, their number equals the number of protons. However, atoms can gain or lose electrons to become ions, which carry either a positive (cations) or negative (anions) charge. The atomic symbol for an element is written as ^{A}_{Z}X{charge}, where X is the element symbol. Understanding these components and their notation is crucial for deciphering the structure of any atom or ion. The atomic number is a fundamental property that uniquely identifies an element, while the mass number reflects the total number of nucleons (protons and neutrons) in the nucleus. The charge indicates whether the atom has gained or lost electrons, affecting its overall electrical state. This detailed understanding forms the foundation for analyzing the given sulfur isotope and determining its correct symbol. By grasping these fundamental concepts, we can confidently approach the problem and arrive at the accurate representation of the sulfur particle.

Step-by-Step Analysis of the Sulfur Isotope

Let's break down the given information to determine the symbol for the sulfur particle. We know that the particle contains 18 neutrons and 18 electrons. To find the atomic symbol, we need to determine the atomic number (Z), the mass number (A), and the charge. Since the particle is an isotope of sulfur, it must have 16 protons. This is because the number of protons defines the element, and sulfur always has 16 protons. Therefore, the atomic number (Z) is 16. The mass number (A) is the sum of protons and neutrons, which in this case is 16 protons + 18 neutrons = 34. To determine the charge, we compare the number of protons and electrons. A neutral atom has an equal number of protons and electrons. In this case, there are 16 protons and 18 electrons. Since there are two more electrons than protons, the particle has a charge of 2-. Now we have all the information needed to write the symbol for the particle. The element symbol for sulfur is S. The atomic number (Z) is 16, and the mass number (A) is 34. The charge is 2-. Therefore, the symbol for this particle is ^{34}_{16}S{2-}. This step-by-step approach allows us to systematically analyze the composition of the sulfur isotope and accurately represent it using the correct atomic symbol. Understanding each component proton, neutron, and electron and their respective contributions to the atomic number, mass number, and charge is essential for solving this type of problem. By carefully applying these principles, we can confidently identify and symbolize any isotope or ion.

Evaluating the Answer Choices A Comprehensive Comparison

Now that we have determined the correct symbol for the sulfur particle, ^{34}_{16}S{2-}, let's evaluate the given answer choices to confirm our result. Answer choice A) ^{34}_{16}S{2+} represents a sulfur isotope with a mass number of 34, an atomic number of 16, and a charge of 2+. This implies that the particle has 16 protons, 18 neutrons, and 14 electrons. This is incorrect because the given particle has 18 electrons, not 14. Answer choice B) ^{34}{16}S represents a neutral sulfur isotope with a mass number of 34 and an atomic number of 16. This means it has 16 protons, 18 neutrons, and 16 electrons. While the mass number and atomic number are correct, the charge is incorrect because the given particle has 18 electrons, not 16. Answer choice C) ^{34}_{16}S{2-} matches our calculated symbol. It represents a sulfur isotope with a mass number of 34, an atomic number of 16, and a charge of 2-. This corresponds to 16 protons, 18 neutrons, and 18 electrons, which aligns perfectly with the given information. Therefore, this is the correct answer. Answer choice D) ^{36}{16}S represents a neutral sulfur isotope with a mass number of 36 and an atomic number of 16. This means it has 16 protons and 20 neutrons. The number of neutrons is incorrect because the given particle has 18 neutrons. By systematically comparing each answer choice with our calculated symbol, we can confidently identify the correct representation of the sulfur particle. This evaluation process reinforces the importance of understanding each component of the atomic symbol and how it relates to the number of protons, neutrons, and electrons in an atom or ion.

Why Option C is the Correct Symbol for the Sulfur Particle

To reiterate, option C, ^{34}_{16}S{2-}, is the correct symbol for the sulfur particle because it accurately represents the given information. The subscript 16 indicates the atomic number, which is the number of protons in the nucleus. Sulfur always has 16 protons, so this part of the symbol is correct. The superscript 34 indicates the mass number, which is the sum of protons and neutrons. In this case, 16 protons + 18 neutrons = 34, so the mass number is also correct. The superscript 2- indicates the charge of the particle. Since the particle has 18 electrons and 16 protons, it has a net charge of 2- because there are two more electrons than protons. This charge is accurately represented in the symbol. Options A, B, and D are incorrect for the following reasons Option A, ^{34}_{16}S{2+}, incorrectly indicates a positive charge of 2+, which would mean the particle has 14 electrons, not 18. Option B, ^{34}{16}S, represents a neutral sulfur atom, which would have 16 electrons, not 18. Option D, ^{36}{16}S, incorrectly indicates a mass number of 36, which would mean the particle has 20 neutrons instead of 18. By thoroughly analyzing each component of the symbol, we can clearly see why option C is the only one that correctly represents the given information about the sulfur particle. This detailed explanation reinforces the importance of understanding the relationship between the atomic number, mass number, and charge in determining the correct symbol for an atom or ion.

Conclusion Mastering Atomic Symbols for Chemical Understanding

In conclusion, the correct symbol for a particle of a sulfur isotope containing 18 neutrons and 18 electrons is ^{34}_{16}S{2-}. This determination was made by carefully analyzing the given information and applying the fundamental principles of atomic structure. We identified the atomic number (Z) as 16 because sulfur always has 16 protons. The mass number (A) was calculated as 34 by summing the protons (16) and neutrons (18). The charge of 2- was determined by comparing the number of protons (16) and electrons (18), indicating a surplus of two electrons. By systematically breaking down the problem and understanding the significance of each component of the atomic symbol, we were able to confidently arrive at the correct answer. This exercise highlights the importance of mastering atomic symbols and their interpretation in the broader context of chemistry. A solid understanding of atomic structure is essential for comprehending chemical reactions, bonding, and the properties of elements and compounds. The ability to accurately represent and interpret atomic symbols is a foundational skill for any aspiring chemist. By mastering these concepts, students can build a strong foundation for further studies in chemistry and related fields.
