Step 1/2

A simplified illustration of the electronic structure of a covalent molecule as well as ion is called a Lewis structure. It was created by American chemist Gilbert N. Lewis within the first decade of the 20th century to represent how valence electrons are arranged around atoms in molecules. Chemistry students can use Lewis structures to better comprehend the bonding as well as geometry of molecules.

Carbon has `4` valenence electrons, Hydrogen has `1` , and Oxygen has `6` . Since there are two Oxygens, there is need to multiply `6` by `2` , which will give `12` . Adding all the valence electrons up to get `17` . However, the overall charge is negative, which means there is an extra electron. Add that to the `17` , and total number of electrons is `18` . The basic structure:

Explanation:

Only the valence electrons of atoms are taken into account in a Lewis structure. The electrons at an atom's outermost energy level (or shell), known as the valence electrons, participate in chemical bonding.

Step 2/2

`6` electrons in the bonds are already added, so only `12` electrons are left to add. Just adding lone pairs to the atoms, the structure is given as:

Completing the octet of oxygen, the final structure is given as:

Explanation:

The octet rule asserts that most atoms tend to add, lose, or share electrons in such a way as to attain a full outer shell of eight electrons, which is the goal of building Lewis structures.

Final Answer

The lewis structure is drawn in step `2` .
