For example, all carbon atoms have 6 protons. However, the number of <strong>neutrons<\/strong> in carbon atoms can vary. These variations are called <strong>isotopes<\/strong>. So, isotopes are atoms of the same element (same number of protons) but with <strong>different numbers of neutrons<\/strong>.<\/p>\n\n\n\n<p>For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Carbon-12<\/strong> has 6 protons and 6 neutrons.<\/li>\n\n\n\n<li><strong>Carbon-13<\/strong> has 6 protons and 7 neutrons.<\/li>\n\n\n\n<li><strong>Carbon-14<\/strong> has 6 protons and 8 neutrons.<\/li>\n<\/ul>\n\n\n\n<p>The difference in neutron number changes the <strong>atomic mass<\/strong> of the isotopes. However, because they have the same number of protons and electrons, isotopes of an element generally behave the same in <strong>chemical reactions<\/strong>. Still, differences in mass can lead to variations in <strong>physical properties<\/strong> or <strong>nuclear behavior<\/strong>. For example, Carbon-14 is radioactive and used in <strong>radiocarbon dating<\/strong>, while Carbon-12 and Carbon-13 are stable.<\/p>\n\n\n\n<p>Isotopes are incredibly important in science. Stable isotopes are used in studies of climate, biology, and medicine, while radioactive isotopes are used in <strong>nuclear power<\/strong>, <strong>medical imaging<\/strong>, and <strong>cancer treatment<\/strong>.<\/p>\n\n\n\n<p>In summary, isotopes are forms of the same element that vary by neutron count. This simple change in the nucleus leads to significant uses across scientific fields without changing the basic chemical identity of the atom.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/04\/image-186.png\" alt=\"\" class=\"wp-image-207215\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>How are isotopes of the same element different from each other?
