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.

true

explanation:

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary
