The number of protons in a neutral atom is always equal to its atomic number, so Chlorine has <strong>17 protons<\/strong>.<\/p>\n\n\n\n<p>The number of electrons in a neutral atom is also 17, as the number of protons and electrons are balanced to make the atom neutral. Therefore, Chlorine has <strong>17 electrons<\/strong>.<\/p>\n\n\n\n<p>To determine the number of neutrons, we need to look at the atomic mass of chlorine. Chlorine has two common isotopes: chlorine-35 (with an atomic mass of approximately 35) and chlorine-37 (with an atomic mass of approximately 37). For simplicity, let&#8217;s use the isotope chlorine-35 as an example.<\/p>\n\n\n\n<p>To find the number of neutrons, subtract the atomic number (protons) from the atomic mass:<br>Neutrons=Atomic&nbsp;Mass\u2212Atomic&nbsp;Number\\text{Neutrons} = \\text{Atomic Mass} &#8211; \\text{Atomic Number}Neutrons=Atomic&nbsp;Mass\u2212Atomic&nbsp;Number<br>For chlorine-35:<br>Neutrons=35\u221217=18\\text{Neutrons} = 35 &#8211; 17 = 18Neutrons=35\u221217=18<\/p>\n\n\n\n<p>Thus, <strong>Chlorine-35 has 18 neutrons<\/strong>.<\/p>\n\n\n\n<p>If you&#8217;re considering chlorine-37, the calculation would be:<br>Neutrons=37\u221217=20\\text{Neutrons} = 37 &#8211; 17 = 20Neutrons=37\u221217=20<br>So, <strong>Chlorine-37 has 20 neutrons<\/strong>.<\/p>\n\n\n\n<p>In summary, Chlorine typically has:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>17 protons<\/strong><\/li>\n\n\n\n<li><strong>17 electrons<\/strong><\/li>\n\n\n\n<li>Either <strong>18 or 20 neutrons<\/strong>, depending on whether it is chlorine-35 or chlorine-37.<\/li>\n<\/ul>\n\n\n\n<p>This distinction between isotopes arises because the number of neutrons can vary, but the number of protons and electrons in a neutral atom of chlorine is fixed.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner6-1206.jpeg\" alt=\"\" class=\"wp-image-262086\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>How many protons, neutrons and electrons does Chlorine have?
