They only need to lose one electron to obtain noble gas configuration and thus it is extremely energetically favorable for them to do this. Rubidium, potassium, sodium and lithium also only need one electron removing. With cesium and francium however, the atoms are much larger making the outer electron much further from the positive nucleus and also shielded by lot more electrons. This makes it extremely easy to remove and thus they are both highly reactive.

∙ 14y agoBecause caesium and francium are alkali metals, the last two in the first group of the Periodic Table of Mendeleev.

∙ 11y agocaesium is larger because of its electrons it has while magnesium has less
Wiki User
∙ 11y agoCaesium has a smaller one - as it is above francium so it has one less outer shell of electrons

How do you prodict that francium would react?
The predictions are based on the supposition that francium is similar to caesium.
Which element has the same properties as cesium?
Only caesium has the same properties as caesium. There are other elements which have some similar properties.
Group 1A elements have similar properties because they?
have the same number of valence electrons, need the same number of electrons to fill their valence shells
Is francium related to water or caesium?
Francium is an alkali metal, similar to caesium. Water (H2O) is a compound,not an element. Francium, although it is believed to have never been tested, is thought to have been the most reactive element with water. It is among the alkali metals in group 1 on the periodic table of elements.
