This number tells the number of <strong>protons<\/strong>, which are positively charged particles located in the nucleus of the atom. Since every element\u2019s identity is defined by its number of protons, all iron atoms must have 26 protons.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In a <strong>neutral<\/strong> atom, the number of <strong>electrons<\/strong>, which are negatively charged particles found outside the nucleus, is equal to the number of protons. Therefore, a neutral atom of iron also contains <strong>26 electrons<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>mass number<\/strong> of an atom is the total number of protons and neutrons in its nucleus. Iron has a mass number of 56. To find the number of <strong>neutrons<\/strong>, subtract the atomic number from the mass number:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">56 (mass number) \u2013 26 (atomic number) = <strong>30 neutrons<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Now, if the iron atom <strong>loses 3 electrons<\/strong>, it will no longer be neutral. The loss of electrons means it has more positive charges than negative ones. Each lost electron results in a +1 charge. So, losing three electrons gives the atom a <strong>+3 charge<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The symbol for an ion is written using the element symbol followed by the charge in superscript. Therefore, the correct symbol for an iron atom that has lost 3 electrons is <strong>Fe\u00b3\u207a<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This positively charged ion is called a <strong>cation<\/strong>. Iron commonly forms +2 or +3 ions in chemical reactions, especially in ionic compounds such as FeCl\u2082 (iron(II) chloride) and FeCl\u2083 (iron(III) chloride). The +3 ion, Fe\u00b3\u207a, is more stable in some oxidation states and often found in biological and industrial processes.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Iron has an atomic number of 26 and a mass number of 56.
