Question

which property would cesium most likely have?○ it is hard.○ it is ductile.○ it is a gas.○ it has low reactivity.

Explanation:

Cesium is an alkali metal, which are all soft, solid metals at standard conditions. Alkali metals are highly reactive, and as a group, they are ductile (can be drawn into wires). Let's eliminate incorrect options:

1. It is hard: Alkali metals are soft, so this is false.
2. It is a gas: Cesium is a solid at room temp, so this is false.
3. It has low reactivity: Alkali metals are the most reactive metals, so this is false.

Answer:

B. It is ductile.
