The <strong>number of protons<\/strong> in an atom determines the <strong>element<\/strong>. This number is called the <strong>atomic number<\/strong>.<\/p>\n\n\n\n<p>In this case, the atom has <strong>3 protons<\/strong>. Looking at the periodic table, the element with atomic number 3 is <strong>lithium (Li)<\/strong>. Therefore, this atom is a lithium atom.<\/p>\n\n\n\n<p>The <strong>mass number<\/strong> of an atom is the total number of <strong>protons and neutrons<\/strong> in its nucleus. Here, the atom has:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>3 protons<\/li>\n\n\n\n<li>4 neutrons<\/li>\n<\/ul>\n\n\n\n<p>So, the mass number = 3 + 4 = <strong>7<\/strong>. This gives us the isotope <strong>lithium-7 (\u2077Li)<\/strong>, which is the most common and stable isotope of lithium found in nature.<\/p>\n\n\n\n<p>The <strong>electrons<\/strong> in an atom determine its <strong>charge<\/strong>. A <strong>neutral atom<\/strong> has the same number of electrons as protons. Since this atom has <strong>3 electrons<\/strong>, and it also has <strong>3 protons<\/strong>, it is <strong>electrically neutral<\/strong>\u2014meaning it is a <strong>neutral lithium-7 atom<\/strong>.<\/p>\n\n\n\n<p>To summarize:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Element<\/strong>: Lithium<\/li>\n\n\n\n<li><strong>Atomic number<\/strong>: 3 (from number of protons)<\/li>\n\n\n\n<li><strong>Mass number<\/strong>: 7 (3 protons + 4 neutrons)<\/li>\n\n\n\n<li><strong>Isotope<\/strong>: Lithium-7 (\u2077Li)<\/li>\n\n\n\n<li><strong>Charge<\/strong>: Neutral (3 protons balanced by 3 electrons)<\/li>\n<\/ul>\n\n\n\n<p>This information helps scientists identify not only the element, but also its isotope and charge state. Understanding atomic structure is fundamental in chemistry and physics because it governs how atoms bond, react, and form the substances that make up all matter.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner10-92.jpeg\" alt=\"\" class=\"wp-image-230741\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>What make an atom that has 3 protons, 4 neutrons, and 3 electrons The Correct Answer and Explanation is: An atom that has 3 protons, 4 neutrons, and 3 electrons is a lithium atom, specifically the lithium-7 isotope.
