Predict the product of burning francium in air.

Short Answer

Expert verified

Francium oxide is produced when francium is burned in air.

Step by step solution

01

Details of francium

  • In the periodic table, francium (Fr) belongs to group IA. It's a valence electron configuration alkali metal having a valence electron configuration of\(7\;{{\rm{s}}^1}\)
  • Alkali metals are highly electropositive, which means they readily lose valence electrons, making them reactive.
02

Reaction of francium when burning

Then burned, francium rapidly interacts with oxygen to produce francium oxide. The following is a representation of the reaction:

\(4{\rm{Fr}} + {{\rm{O}}_2} \to 2{\rm{F}}{{\rm{r}}_2}{\rm{O}}\)

Therefore, francium oxide is produced when francium is burned in air.
