WebS-block elements of the modern periodic table such as lithium and beryllium exhibit unique properties with respect to other elements in the same group due to various reasons. Lithium: Lithium exhibits distinct properties due to the small size of the lithium atom, high polarising power (ratio of charge to the radius) and hydration energy. WebThe base value of hydrogen was later increased by 0.10 and caesium's electronegativity was later refined to 0.79; however, no refinements have been made for francium as no experiment has been conducted. However, francium is expected and, to a small extent, observed to be more electronegative than caesium. See francium for details. Web---This statement has been added.
