Question

The number of essentially different kinds of constituents in a crystal tends to be small...usually less than 4.

A. True
B. False

Answer 1

b) False. There are several different types of crystalline solids, depending on the identity of the units that compose the crystal.

Step-by-step explanation:

False.

There are several different types of crystalline solids, depending on the identity of the units that compose the crystal. The number of essentially different kinds of constituents in a crystal varies depending on the crystal structure and composition.

While it is true that the number tends to be small, it can exceed 4 in certain cases. For example, a crystal composed of sodium chloride (table salt) consists of two different kinds of ions, sodium ions and chloride ions, making it more than 4 different kinds of constituents.
