Lionel has a hot plate, a thermometer, a container of water, a spoon, and a small hammer. using these tools, lionel can test several properties of an ionic compound; however, he will be unable to test the compound’s .
a) atomic structure
b) melting point
c) ability to dissolve
d) brittleness

The correct option is A.

Explanation: Lionel has some of the tools which can be used to detect the physical properties of an ionic compound.

Melting point can be easily detected by using the thermometer.Dissolving ability can be studied when the ionic compound is mixed with a solvent in a container and stirred with the help of a spoon.Brittleness can be detected when the ionic compound is hit with the hammer.But, studying atomic structure is done at a microscopic level. This is a chemical property and cannot be

Hence, the correct option is A.

A) Atomic structure
The atomic structure of a substance cannot be so easily tested, although its effects are visible in the material's physical properties.

Radioactive fallout is a result of the fission creation used to ignite the thermonuclear fusion reaction.

D. h2o + h2o > h3o + oh- confirmed.
