Draw the Lewis structure for Calcium Carbonate (CaCO3<\/p>\n\n\n\n
The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n
Lewis Structure of Calcium Carbonate (CaCO\u2083)<\/strong><\/h3>\n\n\n\n
Calcium carbonate (CaCO\u2083) consists of calcium ions (Ca\u00b2\u207a) and carbonate ions (CO\u2083\u00b2\u207b). Since calcium is a metal, it donates electrons to form a Ca\u00b2\u207a ion, and carbonate is a polyatomic ion with covalent bonds between carbon and oxygen.<\/p>\n\n\n\n
\n\n\n\n
Steps to Draw the Lewis Structure of CO\u2083\u00b2\u207b<\/strong><\/h3>\n\n\n\n\n
Determine the total valence electrons:<\/strong>\n
\n
Carbon (C) has 4 valence electrons<\/strong>.<\/li>\n\n\n\n
Distribute these on oxygen atoms to satisfy the octet rule.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
Check for octets and formal charges:<\/strong>\n
\n
Carbon lacks a full octet, so form a double bond<\/strong> with one oxygen.<\/li>\n\n\n\n
This results in one C=O bond<\/strong> and two C\u2013O\u207b single bonds<\/strong>, where the negative charges reside on the two singly bonded oxygens.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n\n\n\n\n
Final Structure<\/strong><\/h3>\n\n\n\n
\n
Calcium (Ca\u00b2\u207a) does not participate in covalent bonding<\/strong>; it simply balances the charge.<\/li>\n\n\n\n
The final structure consists of:\n
\n
A carbonate ion (CO\u2083\u00b2\u207b)<\/strong> with resonance between the oxygen atoms.<\/li>\n\n\n\n
A Ca\u00b2\u207a ion<\/strong> that interacts electrostatically.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n
Now, I will generate the image of the Lewis structure.<\/p>\n\n\n\n
