Answer:
D: The bond is created by oppositely charged metal and nonmetal atoms.
Explanation:
An ionic metal basically involves a metal and a nonmetal in bonding. A metal is a cation with a + charge and a nonmetal is a anion with a - charge. I will give you an example. Magnesium Chloride is a ionic bond. This is because Magnesium is a metal with a +2 charge(so it is a cation). Chloride or Chlorine is a nonmetal because it has a -1 charge.(so it is a anion). The chemical formula for magnesium chloride is MgCl2.
Hope my answer helped! Have a great day.
Answer: the following are essential factors to be considered when choosing a solvent for crystallization
1. The crystallization solvent should not dissolve the substance to be purified at room temperature, but it should dissolve it well at the solvent’s boiling point
2. The solvent should dissolve soluble impurities well at room temperature.
3. The solvent should not dissolve insoluble impurities even at the solvent’s boiling
point.
4. The solvent must not react with the substance to be purified .
