Name two elements that have properties similar to those of the element sodium

All of these elements have an electron configuration that ends with s1. Francium's properties have not been determined experimentally, because so far there has not been enough of it to experiment with Sodium is group 1/IA, the alkali metals, on the periodic table. Therefore, the other elements in this group will have similar properties as sodium. These would include, lithium, potassium, rubidium, and cesium.

Hope this is the answer

It will fall off and tip over.
