Sodium (Na) is a Group 1 alkali metal that readily loses one electron to form a Na\u207a cation. Since there are two sodium atoms, they each donate one electron, providing a total of two positive charges to balance the -2 charge of the carbonate ion (CO\u2083\u00b2\u207b).<\/p>\n\n\n\n<p>The <strong>carbonate ion (CO\u2083\u00b2\u207b)<\/strong> itself is <strong>a polyatomic ion with covalent bonding<\/strong> among its carbon and oxygen atoms. The Lewis structure of CO\u2083\u00b2\u207b reveals that carbon forms <strong>three bonds with the surrounding oxygen atoms<\/strong>: one double bond and two single bonds. However, due to <strong>resonance<\/strong>, the position of the double bond shifts among the three oxygen atoms. This means the actual structure of CO\u2083\u00b2\u207b is a resonance hybrid, where all three C\u2013O bonds are equivalent and have a bond order of about 1.33.<\/p>\n\n\n\n<p>Thus, <strong>Na\u2082CO\u2083 contains both ionic bonds (between Na\u207a and CO\u2083\u00b2\u207b)<\/strong> and <strong>covalent bonds (within the carbonate ion)<\/strong>.<\/p>\n\n\n\n<p>Regarding the <strong>octet rule<\/strong>, each atom in CO\u2083\u00b2\u207b satisfies the octet rule: carbon has four bonds (8 electrons), and each oxygen has either two bonds and two lone pairs or one bond and three lone pairs, giving each atom a full octet.<\/p>\n\n\n\n<p>Finally, <strong>resonance<\/strong> occurs in Na\u2082CO\u2083 due to the structure of the carbonate ion. As mentioned, the location of the double bond among the oxygen atoms is not fixed, which is a classic sign of resonance. Therefore, Na\u2082CO\u2083 <strong>exhibits resonance<\/strong>, contributing to the stability of the carbonate ion.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Answer the following questions regarding Na2CO3.
