Greater atomic size
WebNow due to excess of electron, electron-electron repulsion becomes greater as compared to electron-proton attraction. On the other hand in Na, it's atomic number is 11, having 11-electrons & 11-protons. After gaining electron, it becomes Na+, having 10-electrons & … WebConsequently, elements in Group 1 have higher atomic radii than elements in their respective periods, and the greater atomic size weakens atomic forces. Because Group 1 elements have wide atomic radii between neighbouring atoms, the melting and boiling points are lower than other metals.

WebThe atomic radius of a chemical element is the distance from the center of the nucleus to the outermost shell of an electron. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. Depending on the definition, the term may apply only to isolated atoms, or also to atoms in condensed matter, … Web119 rows · The Bohr radius is consequently known as the "atomic unit of length". It is often denoted by a 0 and is approximately 53 pm. Hence, the values of atomic radii given here …
