These determine the energy, shape, orientation, and spin of atomic orbitals.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Let\u2019s break down each part of the question using this framework:<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">a. Subshell Designation:<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>principal quantum number (n = 5)<\/strong> represents the energy level or shell. The <strong>azimuthal quantum number (l = 1)<\/strong> describes the subshell and shape of the orbital. The values of <strong>l<\/strong> correspond to subshell letters:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>l = 0 \u2192 s<\/li>\n\n\n\n<li>l = 1 \u2192 p<\/li>\n\n\n\n<li>l = 2 \u2192 d<\/li>\n\n\n\n<li>l = 3 \u2192 f<\/li>\n\n\n\n<li>l = 4 \u2192 g (less common in known elements)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">So, when <strong>n = 5<\/strong> and <strong>l = 1<\/strong>, the subshell is designated <strong>5p<\/strong>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">b. Number of Orbitals:<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The number of orbitals in a subshell is determined by the number of possible values of the <strong>magnetic quantum number (ml)<\/strong>, which ranges from <strong>\u2013l to +l<\/strong>, including 0.<br>For <strong>l = 1<\/strong>, ml can be: \u20131, 0, and +1 \u2014 which means there are <strong>3 orbitals<\/strong>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">c. ml Values:<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">As stated, the ml values for a p subshell (l = 1) are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>ml = \u20131<\/strong><\/li>\n\n\n\n<li><strong>ml = 0<\/strong><\/li>\n\n\n\n<li><strong>ml = +1<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Each orbital can hold <strong>2 electrons<\/strong> with opposite spins (ms = \u00b1\u00bd), so the <strong>5p<\/strong> subshell can accommodate <strong>6 electrons total<\/strong> (3 orbitals \u00d7 2 electrons).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding these quantum numbers helps explain the periodic table\u2019s structure, electron configurations, and the chemical behavior of elements. For example, the 5p subshell begins filling in elements like iodine (I), which influences their reactivity and placement in the periodic table.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner6-70.jpeg\" alt=\"\" class=\"wp-image-227007\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>What is the designation for the subshell with n = 5 and l = 1? b.
