By this definition, hydrogen and helium are sometimes also considered to be part of the s-block.

Construction began on a new eight-storey building that would accompany the C-block and the S-block.

The alkali metals and the alkaline earth metals are in the S-block.

The elements in the s-block generally exhibit well-defined trends in their physical and chemical properties, changing steadily moving down the groups.

The other markets include the local H-block market and a weekly Thursday market near the S-block.

This group lies in the s-block of the periodic table as all alkaline earth metals have their outermost electron in an s-orbital.

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 s-block is a block in the periodic table that consists of the first two groups, namely the alkali metals and the alkaline earth metals.

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.

Although both hydrogen and helium are in the s-block, neither of them behaves similarly to other s-block elements.

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

The s-block comprises the first two groups (alkali metals and alkaline earth metals) as well as hydrogen and helium.

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 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).

Einar Gerhardsens plass 3 and Møllergata 19 (S-block); houses the Ministry of Health and Care Services and the Ministry of Labour.

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.
