12. Most metals share four common physical characteristics. Which of the options is not one of the four? O D. Conductivity
O A Luster
O B. Conductivity
O C. Malleability
O E Reactivity

E Reactivity

Explanation:

Reactivity is not one of the properties shared by metals with one another.

The reactivity of a substance is its ability to combine with other substances. Reactivity is not used to measure the physical property of a metal.

Physical properties are those that we can sense with our senses. For metals, conductivity, luster, malleability are all properties of metals. They can be examined using our active senses.

The physical properties observed in metals derives from the metallic bonds within their atomic structure.

Conductivity, luster, malleability, ductility, magnetism etc. are some of the other physical properties of metals.
