Electron<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<p>Atoms are the fundamental building blocks of matter, and they consist of three primary subatomic particles: protons, neutrons, and electrons. Each of these particles plays a crucial role in defining the atom&#8217;s properties, but their contributions to the atomic mass number vary significantly.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Protons<\/strong> are positively charged particles located in the nucleus of an atom. They have a relatively large mass compared to electrons and contribute significantly to the atomic mass number. The atomic mass number, also known as the nucleon number, is the sum of the number of protons and neutrons in the nucleus of an atom.<\/li>\n\n\n\n<li><strong>Neutrons<\/strong> are neutral particles also found in the nucleus. They have a mass comparable to that of protons and, along with protons, contribute to the atomic mass number. The number of neutrons can vary among atoms of the same element, leading to different isotopes.<\/li>\n\n\n\n<li><strong>Electrons<\/strong> are negatively charged particles that orbit the nucleus. The mass of an electron is significantly smaller than that of protons and neutrons. In fact, the mass of an electron is approximately 1\/1836th of the mass of a proton or neutron. Because of this relatively negligible mass, electrons do not contribute substantially to the atomic mass number.<\/li>\n\n\n\n<li><strong>Quarks<\/strong> are elementary particles that make up protons and neutrons. Protons and neutrons are composed of quarks bound together by the strong force. However, quarks are not typically considered when calculating the atomic mass number, as the mass of protons and neutrons (which are made of quarks) is the more relevant measure for atomic mass.<\/li>\n<\/ul>\n\n\n\n<p>In summary, while electrons are essential for chemical bonding and the overall charge of an atom, their contribution to the atomic mass number is negligible due to their very small mass compared to protons and neutrons. This is why in atomic mass calculations, protons and neutrons are the primary focus.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The component of an atom that possesses relatively little mass, thus being negligible in calculating the atomic mass number, is the: A.Electron B.Quark C.Neutron D.Proton The correct answer and Explanation is : The correct answer is A.
