Question

explain the structure of H2O in English

​

Answer 1

Answer:

Water is a molecule. (H2O) that contains two hydrogen atoms each sharing a pair of electrons with an oxygen atom (see Figure 1). When atoms share electrons in this way, a covalent bondA chemical bond created by the sharing of electrons between atoms. is created. These bonds are essential to living organisms.

Answer 2

$\huge\underline\mathfrak\purple{Answer}$

Oxygen is the central atom in water molecules. The atomic number of oxygen is 8. It has 6 valence electrons and requires 2 more for an octet configuration. The atomic number of hydrogen is 1 and it requires 1 electron to obtain a duet configuration. Therefore, two hydrogen atoms form 1 sigma bond (each) with the central oxygen atom.

The total number of electron pairs in the valence shell of the oxygen atom is 2. Therefore, according to the VSEPR theory, water molecules have a bent shape (they are V-shaped).
