In mathematics, the linear span (also called the linear hull [1] or just span) of a set of elements of a vector space is the smallest linear subspace of that contains . It is the set of all finite linear combinations of the elements of S , [ 2 ] and the intersection of all linear subspaces that contain S . {\displaystyle S.}

Neutral atoms of the chemical elements have the same term symbol for each column in the s-block and p-block elements, but differ in d-block and f-block elements where the ground-state electron configuration changes within a column, where exceptions to Hund's rules occur. Ground state term symbols for the chemical elements are given below.
Span tags were enabled in MediaWiki on December 23, 2004. Polls were held in May and August 2004 on whether the English Wikipedia should enable them. The were equally split between supporting and opposing the addition of these tags. In December, the earlier objections that this would be a semantically void element were deemed to be no longer ...
The group 12 elements zinc, cadmium, and mercury are sometimes regarded as main group, rather than transition group, because they are chemically and physically more similar to the p-block elements than the other d-block elements. The group 3 elements are occasionally considered main group elements due to their similarities to the s-block ...
Taylor Swift is giving fans a glimpse inside her much-talked-about Eras Tour "cleaning cart.". On Wednesday, Dec. 11, Swift, 34, shared a carousel of photos on Instagram from her time onstage ...
Boeing has laid off hundreds of additional employees in Washington state and California as part of planned cuts that will eventually reduce the company's workforce by about 17,000. Nearly 400 ...
Block indicates the periodic table block for each element: red = s-block, yellow = p-block, blue = d-block, green = f-block. Group and period refer to an element's position in the periodic table. Group numbers here show the currently accepted numbering; for older numberings, see Group (periodic table) .
