Webb4 apr. 2024 · Cause of Lanthanide Contraction. The effect of lanthanide contraction results from the poor shielding of nuclear charge (with the attractive nuclear force on electrons) by 4f electrons; the 6s electrons can be drawn towards the nucleus, hence resulting in the smaller atomic radius. In the case of single-electron atoms, the average separation of ...

WebbAtomic radius or Atomic Radii is the total distance from the nucleus of an atom to the outermost orbital of its electron. We define the atomic radius of a chemical element as: The mean or typical distance from the centre … Webb2 okt. 2024 · Whenever an electron shell is filled, adding another electron will cause a step-change in the atomic radius as can be seen in the jagged graph in one of the answers above. Helium turns out to be the smallest atom on that graph, which is one of the reasons it was discovered in the sun before it was discovered on earth. Share.
