Lithium is more metallic than beryllium. Give reason. |
|
Answer» Solution :In lithium the valence electron (in L-shell) is ATTRACTED by three protons of the nucleus, whereas in beryllium the valence electrons PRESENT in L-shell are attracted by four protons in its nucleus. THEREFORE, • It is easier to remove a valence electron from the lithium atom than to remove an electron from the valence shell of a beryllium atom. • Since the metallic character of an element depends on the EASE with which an electron can be removed from its valence shell, lithium is more metallic than beryllium. |
