The s-block is one of four blocks of elements in the periodic table. The element of s- group have a common property. The electron in their most outward electron shell are in the s-orbital.[1] Elements in the s- are in the first two periodic table groups.[2] The elements in group one are called the alkali metals. The elements in group two are called the alkaline earth metals.
The modern periodic law says that "The properties of elements are periodic function of their atomic number." This means that some properties of elements are repeated as the atomic number of the elements gets larger. These repeating properties have been used to separate the elements into four s. These s are s-, p-, d-, and f-.
