Why are all crystals of the mineral halite, NaCl, cubic?

To determine: The crystals of mineral halite, NaCl are cubic in nature.
Answer:
Due the orderly arrangement of particles in three-dimensional array, the crystal structure for, mineral halite, NaCl, is cubic.
Explanation:
The minerals are naturally occurring crystalline solid. This crystalline nature is generated because of ionic bonding present in the minerals. An ionic bond is a bond present between ions. The atoms involved in ionic bonds must have a high difference in electronegativity. The atoms with low electronegativity tend to lose electrons and generate a positive ion and the atoms with high electronegativity tend to gain electrons and generate a negative ion.
The positive and the negative ions tend to attract together by the electrostatic force of attraction and that generates an ionic bond between them. The ionic compounds are usually found in a form of crystals.
In sodium chloride, NaCl, each cation (sodium ion) gets surrounded by six anions (chloride ions) and each negatively charged chloride ion gets surrounded by six cations ( (sodium ions). Therefore, overall, there is only one sodium ion for each chloride ion.
So due the orderly arrangement of particles in three-dimensional array, the crystal structure for, NaCl, is cubic.
Conclusion:
Therefore, due the orderly arrangement of particles in three-dimensional array, the crystal structure for, mineral halite, NaCl, is cubic.

(Figure 1) If it then falls freely (T = 0) from an essentially balanced at-rest position, determine the speed at which the corner A strikes the pad at B. The stone does not slip at its corner C as it falls. Suppose that height of the stone is L = 1.2 ft.

The battery has emf ε = 69 volts and negligible internal resistance. The inductance is L = 0.4 H and the resistances are R 1 = 12 Ω and R 2 = 9.0 Ω. Initially the switch S is open and no currents flow. Then the switch is closed. After leaving the switch closed for a very long time, it is opened again. Just after it is opened, what is the current in R 1?arrow_forward
- A capacitor with a capacitance of C = 5.95×10−5 F is charged by connecting it to a 12.5 −V battery. The capacitor is then disconnected from the battery and connected across an inductor with an inductance of L = 1.55 H . At the time 2.35×10−2 s after the connection to the inductor is made, what is the current in the inductor? At that time, how much electrical energy is stored in the inductor?arrow_forwardCan someone help me with this question. Thanks.arrow_forwardCan someone help me with this question.
