This is because magnesium is an alkaline earth metal (Group 2 of the periodic table), and it tends to lose two electrons to form a 2+ ion.<\/li>\n\n\n\n<li>The perchlorate ion (( \\text{ClO}_4^- )) is a polyatomic ion. In this ion:<\/li>\n\n\n\n<li>Oxygen typically has an oxidation number of -2.<\/li>\n\n\n\n<li>The overall charge of the perchlorate ion is -1.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Let\u2019s calculate the oxidation number of chlorine in ( \\text{ClO}_4^- ).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Calculate the oxidation number of chlorine in the perchlorate ion<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For the perchlorate ion ( \\text{ClO}_4^- ), the sum of the oxidation numbers of all atoms must equal the charge of the ion, which is -1. Let the oxidation number of chlorine in ( \\text{ClO}_4^- ) be ( x ). Since oxygen is typically -2, the four oxygens contribute ( 4 \\times (-2) = -8 ).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The total oxidation number for the ion is:<br>[<br>x + (-8) = -1<br>]<br>Solving for ( x ):<br>[<br>x &#8211; 8 = -1 \\<br>x = +7<br>]<br>Thus, the oxidation number of chlorine in ( \\text{ClO}_4^- ) is +7.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Determine the oxidation number of magnesium<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Now, we know the oxidation number of chlorine in ( \\text{ClO}_4^- ) is +7, and the oxidation number of oxygen in ( \\text{ClO}_4^- ) is -2. The compound ( \\text{Mg(ClO}_4)_2 ) contains two ( \\text{ClO}_4^- ) ions. The total charge from the two ( \\text{ClO}_4^- ) ions is ( 2 \\times (-1) = -2 ).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The overall charge of the compound is neutral, so the charge from magnesium must balance out the total charge of the two ( \\text{ClO}_4^- ) ions. Since the two ( \\text{ClO}_4^- ) ions contribute -2 charge, the magnesium ion must have a +2 charge to balance the equation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Thus, the oxidation number of magnesium (Mg) in ( \\text{Mg(ClO}_4)_2 ) is <strong>+2<\/strong>, as expected from its position in the periodic table and its typical chemical behavior.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>what is the oxidation number of Mg(ClO4)2 The correct answer and explanation is : To determine the oxidation number of magnesium in ( \\text{Mg(ClO}_4)_2 ), we need to analyze the oxidation states of all elements involved in the compound.
