WebMay 24, 2016 · 1) Aluminum is an only Amphoteric** metal element that has the ability to form both ionic and covalent bond. 2) One example of covalent bond is AlCl_3. 3) Al3+ is highly charged species in nature and it can polarize the electron clouds of Cl to a large … WebHence, different compounds tend to have different melting points. A pure, nonionic, crystalline organic compound usually has a sharp and characteristic melting point (usually 0.5-1.0 C range). A mixture of very small amounts of miscible impurities will produce a depression of the melting point and an increase in the melting point range.
