The chemical formula for sodium phosphate is <strong>Na\u2083PO\u2084<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Sodium (Na)<\/strong> is a metal that belongs to the alkali metal group in the periodic table. It has a single electron in its outermost shell and tends to lose that electron to form a cation with a charge of +1 (Na\u207a).<\/li>\n\n\n\n<li><strong>Phosphate (PO\u2084\u00b3\u207b)<\/strong> is a polyatomic ion made up of one phosphorus (P) atom covalently bonded to four oxygen (O) atoms. The phosphate ion has a charge of -3, which is why it attracts positively charged ions to balance the charge.<\/li>\n<\/ol>\n\n\n\n<p>When sodium (Na) combines with phosphate (PO\u2084\u00b3\u207b), the charges must balance out for the compound to be neutral. Sodium ions (Na\u207a) have a +1 charge, and phosphate ions (PO\u2084\u00b3\u207b) have a -3 charge. To balance these charges, three sodium ions (each with a +1 charge) are needed to combine with one phosphate ion (with a -3 charge), resulting in a neutral compound.<\/p>\n\n\n\n<p>Thus, the formula for sodium phosphate is <strong>Na\u2083PO\u2084<\/strong>, indicating three sodium ions for every one phosphate ion.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Formula Derivation:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Sodium ion: Na\u207a<\/li>\n\n\n\n<li>Phosphate ion: PO\u2084\u00b3\u207b<\/li>\n<\/ul>\n\n\n\n<p>To achieve neutrality, the total positive charge must equal the total negative charge. Therefore:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>3 Na\u207a ions (with a total charge of +3)<\/li>\n\n\n\n<li>1 PO\u2084\u00b3\u207b ion (with a charge of -3)<\/li>\n<\/ul>\n\n\n\n<p>This gives the compound <strong>Na\u2083PO\u2084<\/strong>, which is sodium phosphate.
