Question

Which statement is true about the properties of the majority of the elements in the far left column of the periodic table?

A.
They are highly reactive.
B.
They have low electrical conductivity.
C.
They have low heat conductivity.
D.
They have no luster.

Answer 1

A. They are highly reactive

Answer 2

Answer: A. highly reactive is true.

Step-by-step explanation:

The far left column metals are named as Alkali earth metals. Since their ionization energies are low and have larger atomic radii, they are known for their high reactivity. These metals are malleable, ductile. Alkali metals are great conductors of electricity and heat. The most reactive alkali metals in this group are Cesium and Francium. They are shiny, silvery and soft (lustrous).
