Learn which element has the largest atomic radius and why Francium is considered the biggest atom by volume in the periodic table.

330 views

The biggest atom by volume is Francium (Fr), which resides in the alkali metal group of the periodic table. Its large atomic radius is due to its position at the bottom of Group 1, where atoms have more electron shells compared to other elements. However, Francium is extremely rare and radioactive, so it is not commonly encountered in practical scenarios.

FAQs & Answers

  1. Why is Francium considered the biggest atom? Francium has the largest atomic radius because it is located at the bottom of Group 1 in the periodic table, resulting in more electron shells and a larger atomic volume.
  2. Are there atoms bigger than Francium? No, Francium is the biggest atom by volume due to its electron shell configuration, although it is rare and highly radioactive.
  3. What causes atomic size to increase in the periodic table? Atomic size increases down a group because additional electron shells are added, which increases the distance between the nucleus and outer electrons.
  4. Is Francium commonly used in practical applications? Francium is extremely rare and radioactive, so it is not commonly used in practical scenarios or applications.
