Potassium (K) is an alkali metal and has a +1 charge, while sulfate (SO\u2084) is a polyatomic ion with a 2- charge. To balance the charges, two potassium ions (K\u207a) are needed for each sulfate ion (SO\u2084\u00b2\u207b), resulting in the formula K\u2082SO\u2084.<\/p>\n\n\n\n<p><strong>Explanation:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Potassium has an atomic number of 19 and is in Group 1 of the periodic table, which means it typically forms ions with a +1 charge.<\/li>\n\n\n\n<li>Sulfate is a polyatomic ion with the formula SO\u2084\u00b2\u207b, where sulfur (S) is bonded to four oxygen (O) atoms. It carries a 2- charge.<\/li>\n\n\n\n<li>The charges on the potassium and sulfate ions must balance. Since potassium has a +1 charge, two potassium ions are needed to balance the 2- charge of the sulfate ion, leading to the formula K\u2082SO\u2084.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">(b) <strong>Sulfur Hexafluoride (SF\u2086)<\/strong><\/h3>\n\n\n\n<p>Sulfur hexafluoride is a chemical compound made up of sulfur (S) and fluorine (F). In this molecule, sulfur forms six bonds with fluorine atoms, resulting in the formula SF\u2086. Fluorine is a halogen with a 1- charge, so six fluorine atoms (F\u207b) are required to balance the charge of sulfur, which has a neutral charge in this compound.<\/p>\n\n\n\n<p><strong>Explanation:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Sulfur is in Group 16 of the periodic table and has a valence of 6, meaning it can form six bonds.<\/li>\n\n\n\n<li>Fluorine, also in Group 17, is highly electronegative and typically forms a 1- ion.<\/li>\n\n\n\n<li>Each fluorine atom forms a single bond with sulfur, and since sulfur can form up to six bonds, the compound SF\u2086 is stable, with six fluorine atoms bonded to one sulfur atom.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">(c) <strong>Iron(III) Oxide (Fe\u2082O\u2083)<\/strong><\/h3>\n\n\n\n<p>Iron(III) oxide, also known as ferric oxide, is a compound consisting of iron (Fe) and oxygen (O). The Roman numeral III in the name indicates that iron has a +3 charge in this compound. Oxygen, on the other hand, typically has a -2 charge. To balance the charges, two iron ions (Fe\u00b3\u207a) are needed for every three oxide ions (O\u00b2\u207b), which gives the formula Fe\u2082O\u2083.<\/p>\n\n\n\n<p><strong>Explanation:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Iron can have multiple oxidation states, and in Iron(III) oxide, it has a +3 charge.
