Which property would cesium most likely have?
a. it is hard.
b. it is ductile.
c. it is a gas.
d. it has low reactivity.

Option (B) is the correct answer.

Explanation:

Cesium is a group 1A element and therefore, it is a metal. Alkali metals are soft, malleable and ductile.

And, group 1A elements being metals are good conductors of heat and electricity.

Group 1A elements are highly reactive in nature. Hence, cesium is also reactive in nature.  Also, cesium is not a gas.

Therefore, we can conclude that a property cesium would most likely have is that it is ductile.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
