It defines the element. For example, carbon has an atomic number of 6, meaning it has 6 protons.<\/li>\n\n\n\n<li><strong>Mass Number<\/strong>: The mass number is the total number of protons and neutrons in the nucleus of an atom. For example, carbon-12 has a mass number of 12, which means it has 6 protons and 6 neutrons (because the mass number is the sum of protons and neutrons).<\/li>\n<\/ol>\n\n\n\n<p>Now, to find the <strong>number of neutrons<\/strong>, we subtract the <strong>atomic number<\/strong> (which tells us the number of protons) from the <strong>mass number<\/strong> (which tells us the total number of protons and neutrons).<\/p>\n\n\n\n<p>For example, if we look at an atom of carbon-12:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The atomic number of carbon is 6 (it has 6 protons).<\/li>\n\n\n\n<li>The mass number of carbon-12 is 12.<\/li>\n<\/ul>\n\n\n\n<p>To calculate the number of neutrons: Neutrons=Mass&nbsp;number\u2212Atomic&nbsp;number=12\u22126=6\\text{Neutrons} = \\text{Mass number} &#8211; \\text{Atomic number} = 12 &#8211; 6 = 6Neutrons=Mass&nbsp;number\u2212Atomic&nbsp;number=12\u22126=6<\/p>\n\n\n\n<p>Therefore, carbon-12 has 6 neutrons. This formula works for any element. For instance, if we take oxygen-16:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The atomic number of oxygen is 8.<\/li>\n\n\n\n<li>The mass number of oxygen-16 is 16.<\/li>\n<\/ul>\n\n\n\n<p>Neutrons=16\u22128=8\\text{Neutrons} = 16 &#8211; 8 = 8Neutrons=16\u22128=8<\/p>\n\n\n\n<p>So, oxygen-16 has 8 neutrons.<\/p>\n\n\n\n<p>This shows how the mass number and atomic number are related, and how you can easily calculate the number of neutrons in an atom.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-383.jpeg\" alt=\"\" class=\"wp-image-42821\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-383.jpeg 1024w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-383-300x300.jpeg 300w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-383-150x150.jpeg 150w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-383-768x768.jpeg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The number of neutrons in an atom is equal to __. the mass number the mass number + the atomic number the number of protons the mass number &#8211; the atomic number the atomic number The Correct Answer and Explanation is: The correct answer is: the mass number &#8211; the atomic number.
