Group 1 elements have a tendency to lose one electron to achieve a stable electron configuration, specifically the electron configuration of a noble gas (which has a full outer shell). When sodium loses one electron, it forms a <strong>Na\u207a ion<\/strong> with a <strong>1+ charge<\/strong>.<\/li>\n\n\n\n<li><strong>Oxygen (O)<\/strong>, on the other hand, belongs to Group 16 of the periodic table. Oxygen needs two additional electrons to complete its outer shell and reach a stable electron configuration like a noble gas. When oxygen gains two electrons, it forms an <strong>O\u00b2\u207b ion<\/strong> with a <strong>2- charge<\/strong>.<\/li>\n<\/ol>\n\n\n\n<p>For a compound to be stable, the total charge in the formula unit must be neutral. In the case of sodium oxide:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Each sodium atom has a <strong>1+ charge<\/strong>.<\/li>\n\n\n\n<li>Each oxygen atom has a <strong>2- charge<\/strong>.<\/li>\n<\/ul>\n\n\n\n<p>To balance the negative charge of oxygen (O\u00b2\u207b), you need two sodium atoms (Na\u207a), each contributing a 1+ charge. This way, the total positive charge from the two sodium atoms (2 \u00d7 1+ = 2+) balances the total negative charge from the oxygen atom (2-).<\/p>\n\n\n\n<p>Thus, the formula unit for sodium oxide is Na\u2082O because:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Two Na\u207a ions, each with a 1+ charge, are required to balance one O\u00b2\u207b ion with a 2- charge.<\/li>\n<\/ul>\n\n\n\n<p>This principle follows the rule of charge neutrality in ionic compounds, which ensures that the overall charge is zero. Therefore, the formula Na\u2082O reflects this balance, and the compound is electrically neutral.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Why did it require two sodium atoms to complete the na2o formula unit? na has 2 charge and o has -1 charge. na has 1 charge and o has -2 charge. na has -2 charge and o has 1 charge.
