Question

The elements at the bottom of a group would be expected to show:
A.Less metallic property than element at the top
B.More metallic property than element at the top
C.Non-metallic property
D.Metalloid property

Answer 1

Hint:The elements present in the bottom of the periodic tables are mostly radioactive in nature. Their physical and chemical properties are not much known. A transuranium element is any synthetic element having an atomic number greater than that of uranium (92). The atomic number that should be here, 57, is located at the bottom of the table in the row called the Lanthanides. The most radioactive being polonium. The largest first ionization energy containing element is radon and the least being Francium.

Complete step by step answer:
The elements present in the bottom of the periodic table possess more metallic character, the atomic radius of these elements increases, the ionization energy decreases, and the electronegativity decreases as we go down the group. The most metallic character is Francium having atomic number 87.
Thus option B. is the right answer.
The elements at the bottom of a group would be expected to show more metallic property than at the top.

Note:
The highest atomic number synthesized to date is ununoctium (Uuo). Actinide: Any of the 14 radioactive elements of the periodic table that are positioned under the lanthanides, with which they share similar chemistry. Lanthanide: Any of the 14 rare earth elements from lanthanum to lutetium in the periodic table. Because their outermost orbitals are empty, they have very similar chemistry. Below them are the actinides, directly below the space in Row 6, in Row 7, which is another empty space. The extended periodic table with predicted Periods 8 and 9. The periodic table with all groups and periods in place. The placement of the undiscovered g-block is speculative.
