The ductility of a material is the measure of a) the amount of elastic deformation that can be sustained before yielding b) the capacity of a material to absorb energy when it is deformed elastically c) the degree of plastic deformation that has been sustained at fracture. d) the amount of elastic and plastic deformation that can be sustained before reaching the tensile strength

a) the amount of elastic deformation that can be sustained before yielding

Explanation:

ductil material is understood as the one that undergoes great deformations before breaking, it's a property that as such manifests itself once the material is supporting a considerable force.

about the ductility of a material:

→ the percentage of elongation

→ the percentage reduction in the area

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
