Atomic data list

The group 3 elements are sometimes considered main group elements due to their similarities to the s-block elements. Groups (columns) in the f-block (between groups 2 and 3) are not numbered. Helium is an s-block element, with its outer (and only) electrons in the 1s atomic orbital , although its chemical properties are more similar to the p-block noble gases in group 18 due to its full shell. Our table of expanded electron configurations covers 114 elements. Each entry has a full citation identifying its source. Element.
