18 element
There are 4 electronic shells in period 4 while there are 5 shells in period 5.Elements of period 4 are smaller in size as compared to elements of period 5.Example of period 4 element is potassium and period 5 element is tin.
The elements H (Hydrogen) and He (Helium) are in the first period, Ge (Germanium) is in the fourth period, Rb (Rubidium) is in the fifth period, and I (Iodine) is in the fifth period.
There are 2 elements in the first period, 8, 8 elements in 2nd and 3rd periods respectively,
There are 32 elements in the 6th period of the periodic table.

Period 5 in the periodic table includes elements from 37 (Rb) to 55 (Cs). This period consists of transition metals, lanthanides, and actinides, as well as nonmetals and metalloids like iodine and tellurium. Elements in period 5 generally have increasing atomic numbers and atomic masses from left to right.
