Electron dot structure of water class 10

Water is a polar solvent and the bonds between oxygen and hydrogen atoms are polar covalent. We will learn the electron dot structure of water.

The electron dot structure of water will be discussed through the following points.

1.    Formula of water

2.    Electronic configuration of oxygen

3.    Electronic configuration of hydrogen

4.    Find the central atom in the compound

5.    Draw the structural formula of water

6.   Electron dot structure of water

 

Formula of water

`H_2O`

Electronic configuration of oxygen

`1s^2 2s^2 2p^4`

Electronic configuration of hydrogen

`1s^1`

Find the central atom in the compound

As the formula of water shows, there is one Oxygen atom connected to two hydrogen atoms, so oxygen is the central atom.

 Structural formula of water

Oxygen has six valence electrons and requires two electrons to complete the octet.

Hydrogen has one valence electron and requires one more electron to complete the octet.

Oxygen and hydrogen share one -one electron to form a covalent bond.

Oxygen is an electronegative element so it attracts shared electrons to a greater extent than hydrogen atoms.

The oxygen atom possesses a partial negative charge(`\delta-`)  and hydrogen possesses a partial positive charge (`\delta+`).

Due to this bond between oxygen and hydrogen atoms bends.

Following is the water molecule structure
