f-block elements Actinides and lanthanides, the f-block elements, are used in a wide variety of fields including telecommunications, medicine, imaging, sensors, energy, catalysis, and data storage. However, compared to other blocks in the periodic table, f-elements remain underexplored. Deepening ...
Each group 1 element has a valence electron configuration of s1 . Each group 2 element has a valence electron configuration of s2 . Each column in groups 1, 2, and 13 to 18 on the periodic table has its own valence electron configuration. 第1组元素各原子的价电子组态为s1. 第2组元素各原...

F-Block Elements on the Periodic Table Elements that belong to the F-block are elements that have their valence electrons in the f orbital which allows up to 14 electrons before being filled. Elements belonging to the F-block include the lanthanide and actinide g...
It has atomic number 1 and symbol H in the periodic table. Hydrogen is known for its role in the formation of water and its usage as a fuel source. 2. Helium (He) Helium is a noble gas with atomic number 2 and symbol He. It is the second lightest element and is primarily used ...
Image showing periodicity of the chemical elements for valence f-orbital R(max) in a 3D periodic table column style. Units Notes Values given in the original literature are in atomic units (= 52.92 pm). Values given here in pm here are obtained by multiplying the original value 52.92. ...
