Final answer:
Other than space, temperature and the presence of necessary elements are the two significant factors for a crystal to attain its habit. Temperature influences solubility which is crucial for crystal growth, while necessary elements serve as the building blocks for the crystal lattice.
Step-by-step explanation:
Factors Influencing Crystal Habit
The question is asking about the significant factors other than space that are necessary for a crystal to attain its habit. The two additional factors that are crucial for crystal growth are temperature and presence of necessary elements or nutrients.
Temperature plays a significant role in the solubility of substances, which in turn affects the formation of crystals. The solubility of most solids and liquids tends to increase with higher temperatures, which can affect the size and quality of the crystals formed. When it comes to gases, solubility decreases with an increase in temperature, as stated by Henry's Law, which also describes the relationship between pressure and the gas solubility. Furthermore, the availability of the necessary elements or ions in the right ratio is imperative for crystal formation as these are the building blocks of the crystal lattice. Lattice energy, which depends on the crystal structure, is directly influenced by the presence and proper arrangement of these ions.
Thereby, a combination of temperature and necessary elements contributes significantly to a crystal achieving its characteristic habit, which includes size, shape, and form.
