Classify each of the following solids as ionic, metallic, molecular, network (covalent) or amorphous:

(i) Tetra phosphorous decoxide (P4O10) 

(ii) Ammonium phosphate (NH4)3PO4

(iii) SiC

(iv) I2 

(v) P4

(vi) Plastic

(vii) Graphite

(viii) Brass

(ix) Rb

(x) LiBr

(xi) Si 

 

 

Solution:

(i) Tetra phosphorous decoxide (P4O10) - Molecular

(ii) Ammonium phosphate (NH4)3PO4 – Ionic

(iii) SiC - Covalent (network)

(iv) I2 - Molecular

(v) P4 - Molecular

(vi) Plastic - Amorphous

(vii) Graphite – Covalent (network)

(viii) Brass - Metallic

(ix) Rb - Metallic

(x) LiBr - Ionic

(xi) Si – Covalent (network)
