The Roman numeral <strong>(II)<\/strong> in the name indicates the oxidation state of the titanium ion, which is <strong>+2<\/strong> in this compound.<\/p>\n\n\n\n<p>To determine the correct chemical formula, we need to balance the charges of the ions involved:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Titanium (Ti\u00b2\u207a)<\/strong>: Titanium, in the +2 oxidation state, loses two electrons, forming a <strong>Ti\u00b2\u207a<\/strong> ion.<\/li>\n\n\n\n<li><strong>Selenium (Se\u00b2\u207b)<\/strong>: Selenium, a group 16 nonmetal, typically gains two electrons to achieve a stable octet, forming a <strong>Se\u00b2\u207b<\/strong> ion.<\/li>\n<\/ul>\n\n\n\n<p>When combining these ions into a neutral compound, we need one Ti\u00b2\u207a ion and one Se\u00b2\u207b ion. This is because the +2 charge from titanium exactly cancels out the \u22122 charge from selenium. The resulting formula is:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><strong>TiSe<\/strong><\/p>\n<\/blockquote>\n\n\n\n<p>This 1:1 ratio ensures the compound is electrically neutral, which is a fundamental requirement for all stable ionic compounds.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Additional Notes:<\/h3>\n\n\n\n<p>Titanium (II) selenide belongs to a class of compounds known as <strong>transition metal chalcogenides<\/strong>. These materials often have interesting electronic properties and are studied for use in semiconductors, batteries, and other advanced technologies.<\/p>\n\n\n\n<p>TiSe is also known for forming a layered crystal structure, similar to graphite, which allows for potential use in nanotechnology and materials science. It exhibits <strong>charge density wave (CDW)<\/strong> behavior, which is a quantum mechanical phenomenon associated with low-dimensional materials.<\/p>\n\n\n\n<p>In summary, by using ionic charges to balance the components of titanium (II) selenide, we determine that the correct chemical formula is <strong>TiSe<\/strong>, with a 1:1 ratio of titanium and selenium atoms.<\/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-banner6-38.jpeg\" alt=\"\" class=\"wp-image-225214\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>What is the formula for Titanium (II) selenide The Correct Answer and Explanation is: Correct Formula for Titanium (II) Selenide: TiSe Explanation Titanium (II) selenide is a binary compound composed of the elements titanium (Ti) and selenium (Se).
