P-block

The group of elements after the transition metals are the P-block.

The p-block is the only region of the periodic table to contain metalloids.

The trivial name poor metals is sometimes applied to the metallic elements in the p-block of the periodic table.

All elements in the p-block have their outermost electron in a p-subshell.

In 1927, he proposed the inert pair effect which describes the stability of heavier p-block in an oxidation state two less than the maximum.

The p-block of the periodic table of the elements consists of the last six groups except helium (which is located in the s-block).

The position of helium is almost always above neon (which is in the p-block) in the periodic table because it is a noble gas,.

The first two, sodium and magnesium, are members of the s-block of the periodic table, while the others are members of the p-block.

The p-block is one of two blocks in the periodic table to contain nonmetals (although the s-block only contains one nonmetal, hydrogen).

In the s-block and p-block of the periodic table, similar properties across the periods are generally not observed: the most important similarities tend to be vertical, down groups.

The p-block contains all of the nonmetals (except for hydrogen and helium, which are in the s-block) and semimetals, as well as the post-transition metals.

The d-block contraction, which is a similar effect between the d-block and p-block, is less pronounced than the lanthanide contraction but arises from a similar cause.

The table can also be deconstructed into four rectangular blocks: the s-block to the left, the p-block to the right, the d-block in the middle, and the f-block below that.

In the s-block and p-block of the periodic table, elements within the same period generally do not exhibit trends and similarities in properties (vertical trends down groups are more significant).

Typically, the stable electron configuration is one of the noble gases for elements in the s-block and the p-block, and particular stable electron configurations for d-block and f-block elements.

Plus," he added, and appeared to swell with self-importance, "once a week I cart the specimens that need to be disposed of over to P-Block, where liquid and solid waste is rendered and sterilized.

On a standard periodic table all of these elements can be found in or near a diagonal region of the p-block, having its main axis anchored by boron at one end and astatine at the other.

Helium is almost always placed above neon (which is in the p-block) in the periodic table as a noble gas, although it is occasionally placed above beryllium due to their similar electron configuration.

In general, the farther one goes to the right, and the farther one goes up in the p-block, the less metallic the elements get; the metalloids form a diagonal line from the upper left to the lower right of the p-block.

Puig is interested in the generalization of this situation to fusion systems, a categorical model of the fusion pattern of a Sylow p-subgroup with respect to a finite group that also models the fusion pattern of a defect group of a p-block in modular representation theory.

The p-core of a finite group is the intersection of the kernels of the irreducible representations over any field of characteristic p. For a finite group, the p'-core is the intersection of the kernels of the ordinary (complex) irreducible representations that lie in the principal p-block.
