Question

explain binding forces and constituent particles in metallic solids​

Answer 1

Answer:

Ionic Solids:-  

In these solids constituent particles are positive and negative ions. (cation or anions). They are held together by strong columbic electrostatic forces of attraction examples are NaCl, CaCl2, MgCl2, BaCl2 etc.

Characteristics of ionic solids:-

They have high melting and boiling points

They are soluble in polar solvents but are insoluble in non polar solvents.

Due to strong electrostatic forces of attraction they are closely packed hence hard but they are brittle.

2. Molecular Solids:-

In these solids the constituent particles are molecules on the nature of molecules they can further subdivided into following three types:-

1. Non polar molecular solids:-

The crystalline solids in which constituent particles are atoms of noble gases [helium, neon] or non polar molecules like [H2, Cl2, I2]

Explanation:

Answer 2

Answer:

Metallic Solids...

In these solids, constituent particles are positively charged metal ions called Kernels and free electrons. These electrons can easily flow throughout the metal crystal like water in the sea....
