To understand how this compound forms, let\u2019s examine the valence electron configuration of both elements and how they interact:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Magnesium (Mg)<\/strong> is an alkaline earth metal in Group 2 of the periodic table. It has an atomic number of 12 and an electron configuration of [Ne] 3s\u00b2. Since magnesium is in Group 2, it readily loses two electrons to achieve a stable electron configuration, similar to the nearest noble gas (Neon). This results in a Mg\u00b2\u207a ion.<\/li>\n\n\n\n<li><strong>Phosphorus (P)<\/strong> is a non-metal in Group 15 with an atomic number of 15 and an electron configuration of [Ne] 3s\u00b2 3p\u00b3. Phosphorus tends to gain three electrons to achieve a stable electron configuration, similar to the nearest noble gas (Argon), resulting in a P\u00b3\u207b ion.<\/li>\n<\/ol>\n\n\n\n<p>When magnesium and phosphorus combine, the Mg\u00b2\u207a ions and P\u00b3\u207b ions come together in a way that the charges balance out. For every three Mg\u00b2\u207a ions, two P\u00b3\u207b ions are needed to neutralize the charges. This results in the formula Mg\u2083P\u2082, where:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>3 magnesium ions (Mg\u00b2\u207a) contribute a total charge of +6.<\/li>\n\n\n\n<li>2 phosphorus ions (P\u00b3\u207b) contribute a total charge of -6.<\/li>\n<\/ul>\n\n\n\n<p>Thus, the ionic compound formed is <strong>Magnesium Phosphide (Mg\u2083P\u2082)<\/strong>, which has a ratio of three magnesium ions to two phosphorus ions.<\/p>\n\n\n\n<p>The other options listed are incorrect because they do not maintain charge balance:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A (Mg\u2082P\u2083)<\/strong> and <strong>D (Mg\u2082P\u2083)<\/strong> would result in an unbalanced charge distribution.<\/li>\n\n\n\n<li><strong>C (Mg\u2083P\u2082)<\/strong> is the correct formula and is also the name of the compound.<\/li>\n<\/ul>\n\n\n\n<p>Therefore, the compound formed between magnesium and phosphorus is correctly named <strong>Magnesium Phosphide<\/strong>, and its formula is <strong>Mg\u2083P\u2082<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is the formula and name of the compound formed between Mg and P?
