Period two of periodic table
WebThe first period has less elements than any other periods in the periodic table. There 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 ...
