Isotopes are atoms of the same element that have the same number of protons but a different number of neutrons. Since the number of protons defines the element, all oxygen atoms have exactly <strong>8 protons<\/strong>. The number of neutrons, however, can vary.<\/p>\n\n\n\n<p>The <strong>mass number<\/strong> of an atom is the sum of its protons and neutrons. For oxygen, if there are 8 protons and 10 neutrons, the total mass number is:<\/p>\n\n\n\n<p><strong>8 (protons) + 10 (neutrons) = 18<\/strong><\/p>\n\n\n\n<p>Therefore, this isotope of oxygen has a mass number of 18 and is written as <strong>Oxygen-18<\/strong> or <strong>\u00b9\u2078O<\/strong>. It can also be expressed in nuclear notation as:<\/p>\n\n\n\n<p><strong>\u2088\u00b9\u2078O<\/strong><\/p>\n\n\n\n<p>In this notation, the number at the top left (18) is the mass number and the number at the bottom left (8) is the atomic number, which equals the number of protons.<\/p>\n\n\n\n<p>Oxygen has several stable isotopes, and the most common are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Oxygen-16 (\u00b9\u2076O)<\/strong>: 8 protons and 8 neutrons<\/li>\n\n\n\n<li><strong>Oxygen-17 (\u00b9\u2077O)<\/strong>: 8 protons and 9 neutrons<\/li>\n\n\n\n<li><strong>Oxygen-18 (\u00b9\u2078O)<\/strong>: 8 protons and 10 neutrons<\/li>\n<\/ul>\n\n\n\n<p>Oxygen-18 is a stable isotope, although it is less abundant than Oxygen-16. It has important applications in environmental and climate science. Scientists often study the ratio of Oxygen-18 to Oxygen-16 in ice cores and ocean sediments to infer past temperatures and climate conditions. This is possible because the two isotopes behave slightly differently during processes like evaporation and condensation.<\/p>\n\n\n\n<p>In summary, an oxygen atom with 10 neutrons is called <strong>Oxygen-18<\/strong>, and it is a stable and naturally occurring isotope of oxygen used in various scientific fields.<\/p>\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-banner8-1147.jpeg\" alt=\"\" class=\"wp-image-39267\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1147.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1147-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1147-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>An oxygen atom with 10 neutrons Express your answer as an isotope.
