The correct electron configuration for sulfur (atomic number 16) is:<br>S:1s22s22p63s23p4\\text{S}: 1s^2 2s^2 2p^6 3s^2 3p^4S:1s22s22p63s23p4<br>Sulfur has 16 electrons, so its electron configuration follows the Aufbau principle, filling the lower energy orbitals first. The correct arrangement is:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>1s^2 (2 electrons)<\/li>\n\n\n\n<li>2s^2 (2 electrons)<\/li>\n\n\n\n<li>2p^6 (6 electrons)<\/li>\n\n\n\n<li>3s^2 (2 electrons)<\/li>\n\n\n\n<li>3p^4 (4 electrons)<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Question 2: Electron Affinity of Sulfur (S)<\/h3>\n\n\n\n<p>Electron affinity is defined as the energy released when an electron is added to a neutral atom in the gas phase. The correct reaction that represents the electron affinity of sulfur is:<\/p>\n\n\n\n<p><strong>E) S(g) + e\u207b \u2192 S\u207b(g)<\/strong><\/p>\n\n\n\n<p>This is the correct representation of an atom (S) gaining an electron to form an anion (S\u207b). The other options involve incorrect species or reactions that do not represent electron affinity.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A)<\/strong> Incorrect because the reaction describes the dissociation of an anion (S\u207b) into an atom (S) and an electron, which is the opposite of electron affinity.<\/li>\n\n\n\n<li><strong>B)<\/strong> Incorrect as it involves a negative ion (S\u207b) gaining an electron, which is not an electron affinity process.<\/li>\n\n\n\n<li><strong>C)<\/strong> Incorrect because it involves potassium (K) and sulfur, which is unrelated to sulfur&#8217;s electron affinity.<\/li>\n\n\n\n<li><strong>D)<\/strong> Incorrect because it involves the formation of S\u00b2\u207b, which would relate to an electron affinity step that would involve two electrons.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Question 3: Correct Quantum Numbers<\/h3>\n\n\n\n<p>Quantum numbers describe the properties of atomic orbitals. The correct set of quantum numbers from the choices is:<\/p>\n\n\n\n<p><strong>C) n = 3, l = 2, m = 1<\/strong><\/p>\n\n\n\n<p>Explanation:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>n = 3<\/strong>: This is the principal quantum number, which determines the energy level of the orbital.<\/li>\n\n\n\n<li><strong>l = 2<\/strong>: This is the azimuthal (angular momentum) quantum number. It indicates the type of orbital (0 = s, 1 = p, 2 = d, 3 = f). For l = 2, this corresponds to a d orbital.<\/li>\n\n\n\n<li><strong>m = 1<\/strong>: This is the magnetic quantum number, which determines the orientation of the orbital. For a d orbital (l = 2), m can range from -2 to +2, so m = 1 is valid.<\/li>\n<\/ul>\n\n\n\n<p>Let&#8217;s look at why the other choices are incorrect:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A) n = 3, l = 7, m = -3<\/strong>: This is not possible because l must be between 0 and n-1, so l = 7 is invalid for n = 3.<\/li>\n\n\n\n<li><strong>B) n = 3, l = 1, m = +2<\/strong>: This is not valid because when l = 1 (a p orbital), m can only range from -1 to +1, so m = +2 is invalid.<\/li>\n<\/ul>\n\n\n\n<p>Thus, the correct set of quantum numbers is <strong>C) n = 3, l = 2, m = 1<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Summary:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Electron Configuration for S<\/strong>: Correct configuration is [Ne] 3s\u00b2 3p\u2074.<\/li>\n\n\n\n<li><strong>Electron Affinity for S<\/strong>: The correct reaction is <strong>E) S(g) + e\u207b \u2192 S\u207b(g)<\/strong>.<\/li>\n\n\n\n<li><strong>Correct Quantum Numbers<\/strong>: The correct set is <strong>C) n = 3, l = 2, m = 1<\/strong>.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"852\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1487.jpeg\" alt=\"\" class=\"wp-image-44248\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1487.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1487-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1487-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>C) [Ar]3d^6 4s^23d^3 6) Which reaction below represents the electron affinity of S?
