Question

Which alkali metal bicarbonate does not exist as solid at room temperature?

Answer 1

The alkali metals make up Group 1 of the periodic table. This family consists of the elements lithium, sodium, potassium, rubidium, cesium, and francium (Li, Na, K, Rb, Cs, and Fr, respectively). Group one elements share common characteristics. They are all soft, silver metals. Due to their low ionization energy, these metals have low melting points and are highly reactive. The reactivity of this family increases as you move down the table.

Answer 2

It's is because LiLi is in diagonal relationship with MgMg in periodic table. As magnesium hydrogen carbonate is not obtained in solid form, LiHCO3LiHCOX3 also cannot be since both have similar properties.
