1. The sixth period of P block elements in the periodic table begins with atomic number 81 and finishes with atomic number 86. 83, a P block element, so lies in the middle of them.
2. The fifth period of P block elements in the periodic table begins with the atomic number 49 and concludes with 54. Therefore, 54 is a P block element and a member of the halogen family.
3. The fourth period of P block elements in the periodic table runs from 31 to 66. 34 is a P block element since it lies in the middle of them.
Contrarily, atomic numbers 79 and 42 belong to the block, although atomic number 64 does not.

P block elements are three elements that, respectively, have an atomic number of 86, 54, and 34.
