Question

Identify the type of crystalline solid (metallic, network covalent, ionic, or molecular) formed by each of the following substances:

(a) CaCl₂

(b) SiC

(c) N₂

(d) Fe

(e) C (graphite)

(f) CH₃CH₂CH₂CH₃

(g) HCl

(h) NH₄NO₃

(i) K₃PO₄

(j) Cu

Answer 1

CaCl₂ is an ionic solid, SiC is a covalent network solid, N₂ is a molecular solid, Fe is a metallic solid, C (graphite) is a covalent network solid, CH₃CH₂CH₂CH₃ is a molecular solid, HCl is a molecular solid, NH₄NO₃ is an ionic solid, K₃PO₄ is an ionic solid, and Cu is a metallic solid.

Step-by-step explanation:

(a) CaCl₂ - Ionic Solid

(b) SiC - Covalent Network Solid

(c) N₂ - Molecular Solid

(d) Fe - Metallic Solid

(e) C (graphite) - Covalent Network Solid

(f) CH₃CH₂CH₂CH₃ - Molecular Solid

(g) HCl - Molecular Solid

(h) NH₄NO₃ - Ionic Solid

(i) K₃PO₄ - Ionic Solid

(j) Cu - Metallic Solid
