Every chemical element in the periodic table is located in a certain row (period) and column (group). Both of these features indicate certain important electronic properties present in the atom of the element. This includes the number of valence electrons in the uncharged atom. Each element...

Addition of CE completes the periodic table by resolving its existing shortcomings and as a consequence its chemical bonding organizing power is greatly enhanced. CE values match the two best established electronegativity scales, are strongly correlated with atomic energy level spacings, and have a '...

The Bug work item type uses some bug-specific fields. To capture both the initial issue and ongoing discoveries, use the fields described in the following table. For information about fields specific to the Bug defined for the Capability Maturity Model Integration (CMMI) process, see Bugs, ...
Describe the trend in electronegativity going down a group. What is electronegativity and how does it relate to the periodic table? What is meant by electronegativity? How is the difference in electronegativity between two bonded atoms related to the polarity of the bond?

Intestinal stromal cells are known to modulate the propagation and differentiation of intestinal stem cells1,2. However, the precise cellular and molecular mechanisms by which this diverse stromal cell population maintains tissue homeostasis and repair are poorly understood. Here we describe a subset of...
