Question

Which element ,cesium or francium easily loses electron ? Justify your answer in terms of atomic size and attraction towards the positive nucleus

Answer 1

Francium easily loses electrons than cesium

Explanations:

Both Cesium and Francium are Group 1 elements (Alkali metals). This shows that the elements in this group have one valence electron in their outermost shell and can easily lose this electron to form a stable atom.

According to the element in the group, Lithium has the least tendency to loose its valence electron while Francium has the highest tendency to lose its valence electron because its outermost electron gets further from the positive nucleus and less attracted by the nucleus compared to the Caesium element.

Also, the atomic size of Francium is greater than that of Caesium. This also shows that francium easily loses electrons than cesium
