Question

Question: Explain the relationship between the number of bonds that can be formed by a typical atom in a crystal and the possibility of forming linear, two-dimensional, and three-dimensional network structures

Short answer

Answer:

All the different types of bonds present in different molecules are found in nature in their 3Darrangemnt of the crystal lattice.

The three types of arrangement of the ionic compound NaCl are discussed below.

Step-by-step solution

The number of bonds that can be formed by a typical atom in a crystal.

The number of bonds that can be formed by a typical atom in a crystal can be Ionic, Covalent, or Metallic.

Ionic bondsare present between two atoms with a huge electronegativity difference.

Covalent bonds are present between the two atoms because of sharing of electrons.

Metallic bondsare present in metals because of the sea of mobile electrons found around the fixed Na⁺ions positive CI^- ions.

The two-dimensional arrangement of the structure is shown below. The diagram shows that four chlorine ions form a tetrahedral void in which the sodium ion gets fit.

Now the three-dimensional network structuresshow the crystal lattice of NaCl.

Here, the bigger spheres are the chlorine ions, and the smaller ones are sodium ions.
