Question

6. Draw the electron distribution diagram for the formation of Carbon dioxide
(CO2) molecule.​

Answer 1

$\huge\mathfrak \pink{answer}$

Electron distribution diagram is also known as Lewis-dot structure.

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The given molecule is, CO_2CO2

As we know that carbon has '4' valence electrons and oxygen has '6' valence electrons.

Therefore, the total number of valence electrons in CO_2CO2 = 4 + 2(6) = 16

According to Lewis-dot structure, there are 8 number of bonding electrons and 8 number of non-bonding electrons.

Answer 2

●EXPLANATION:●

Carbon dioxide (chemical formula CO2) is a colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas. The current concentration is about 0.04% (412 ppm) by volume, having risen from pre-industrial levels of 280 ppm.[8] Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, ice caps, glaciers and seawater. It is present in deposits of petroleum and natural gas. Carbon dioxide has a sharp and acidic odor and generates the taste of soda water in the mouth.[9] However, at normally encountered concentrations it is odorless.
