These are elements that can be found in nature either in pure form or as part of compounds.<\/p>\n\n\n\n<p>The <strong>periodic table<\/strong> consists of over 100 elements, but not all of them are naturally occurring. The elements beyond atomic number 92, which is <strong>uranium<\/strong>, are called <strong>transuranic elements<\/strong>. These do not occur naturally in significant amounts and are typically produced in laboratories through nuclear reactions. Examples of these synthetic elements include <strong>plutonium (94)<\/strong> and <strong>americium (95)<\/strong>.<\/p>\n\n\n\n<p>Here\u2019s a breakdown:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Hydrogen (1)<\/strong> to <strong>Uranium (92)<\/strong> are naturally occurring.<\/li>\n\n\n\n<li>Some of these elements, such as <strong>technetium (43)<\/strong> and <strong>promethium (61)<\/strong>, are technically not found in large amounts in nature, but they can appear in trace amounts due to radioactive decay or cosmic ray interactions.<\/li>\n\n\n\n<li>Scientists recognize <strong>92 elements<\/strong> as having natural isotopes that can be found somewhere on Earth without needing to be made in a lab.<\/li>\n<\/ul>\n\n\n\n<p>These naturally occurring elements include gases (like <strong>oxygen<\/strong> and <strong>nitrogen<\/strong>), metals (like <strong>iron<\/strong>, <strong>gold<\/strong>, and <strong>silver<\/strong>), and nonmetals (like <strong>carbon<\/strong> and <strong>sulfur<\/strong>). They are the building blocks of all matter found on Earth and in living organisms.<\/p>\n\n\n\n<p>Understanding which elements are natural helps scientists in various fields, including <strong>chemistry, geology, biology, and environmental science<\/strong>. It also assists in tracing the history of the Earth, studying natural processes, and managing natural resources.<\/p>\n\n\n\n<p>To summarize, <strong>92 elements<\/strong> are found in nature, and everything around us is made from different combinations of these basic building blocks.<\/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-banner8-756.jpeg\" alt=\"\" class=\"wp-image-236891\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>How many elements occur naturally on Earth?
