Isotopes.<\/p>\n<p>Isotopes are atoms of the same element that have different numbers of neutrons. They have the same number of protons, which determines the chemical element, but different numbers of neutrons, which determine the isotope. The number of protons and neutrons in the nucleus of an atom is called the atomic mass number.<\/p>\n<p>For example, carbon-12 has 6 protons and 6 neutrons, while carbon-14 has 6 protons and 8 neutrons. Both carbon-12 and carbon-14 are isotopes of carbon, but they have different atomic mass <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div> numbers.<\/p>\n<p>Isotopes are important in many fields, including chemistry, physics, and biology.
