Therefore the correct option would be Indicators are weak acids or bases.
Answer:
a) Molecular crystal
b) Molecular crystal
c) Molecular crystal
d) Ionic crystal
e) Metallic crystal
f) Covalent crystal
g) Ionic crystal
h) Metallic crystal
Explanation:
The bonds between the elements can be classified as ionic, covalent or metallic. The ionic bonds happen between a metal and a nonmetal, where the metal donates electrons and the nonmetal gain the electrons, forming ions. When this occurs, the solid formed is called ionic crystals, such as KBr and LiCl.
When the bond is between nonmetals, its called a covalent bond, and the nonmetals share pair of electrons. When a solid is formed, it can be called as covalent crystals or molecular crystals. The molecular crystals are formed by a determined number of electrons such as CO₂, Br₂ and S₈. On the other hand, the covalent crystals are polymolecular, such as the silica, SiO₂.
When metals do bonds between them, the bond is called a metallic bond, which can happen between atoms of the same element or different elements. The solid formed is called metallic crystal, such as Mg, and Cr.
