Question

What is the biggest element?

Answer 1

1. The biggest element of the periodic table is Francium ($\mathrm{Fr}$) is a naturally occurring and radioactive element which comes under alkali metals.
2. It belongs to Group 1 and Period 7 with the electronic configuration of $1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^{6}4{\mathrm{s}}^{2}3{\mathrm{d}}^{10}4{\mathrm{p}}^{6}5{\mathrm{s}}^{2}4{\mathrm{d}}^{10}5{\mathrm{p}}^{6}6{\mathrm{s}}^{2}4{\mathrm{f}}^{14}5{\mathrm{d}}^{10}6{\mathrm{p}}^{6}7{\mathrm{s}}^1$.
3. The atomic number and atomic weight of this element are 87 and 223 ${\mathrm{gmol}}^{-1}$.
4. This is strongly basic in nature of higher valence oxides.
5. It is a crystal structure with a solid matter at $20°\mathrm{C}$.
6. The ionic radius and ionization enthalpy is $180\mathrm{pm}$ and $375{\mathrm{kJmol}}^{-1}$.
