282 views

Francium is the largest atom due to its high number of electron shells, which makes it larger in size compared to other elements. Its low ionization energy and high reactivity also contribute to its significant atomic radius.

FAQs & Answers

  1. Why is francium the largest atom? Francium has the largest atomic radius due to its high number of electron shells, which increases its size compared to other elements.
  2. How does the number of electron shells affect atomic size? More electron shells increase the distance between the nucleus and the outermost electrons, resulting in a larger atomic radius.
  3. What factors contribute to francium's low ionization energy? Francium's large atomic radius and the shielding effect from inner electrons reduce the attraction between the nucleus and outer electrons, leading to low ionization energy.
