WebIn the current terminology, the first three periods consist of the alkali and alkaline-earth metals, which are i-elements of Subgroups I-A and II-A (indicated by an asterisk in Figure 1) and of the p-elements B through Ne and Al through Ar, which are in Subgroups III-A through VIII-A (indicated by a double asterisk). WebThere are only two elements in the first period: hydrogen and helium. We can explain why there is less elements in the first row in modern theories of atomic structure. This is because in quantum physics, this period fills up the 1s orbital. Period 1 elements follows the duet rule, they only need two electrons to complete their valence shell.
