li salt are predominatly covalent while na salt are predominantly ionivc |
Answer» The\xa0salts\xa0of\xa0alkali metals\xa0are the\xa0most ionic salts\xa0known. Although\xa0lithium\xa0is an\xa0alkali metal\xa0yet its compounds., particularly halides, are slightly\xa0covalent in nature. This is because the\xa0Li* ion has small size and has maximum tendency to withdraw the electrons towards itself from the negative ion.\xa0The atomic and ionic radii of\xa0Li\xa0are very small. Therefore, the nuclear attraction is strong compared to the rest of the alkali metals, which leads to a greater polarising power in\xa0Li\xa0ion, and the formation of\xa0covalent\xa0bonds. | |
