Question

Nuclear energy is produced when scientists force uranium (U) atoms to break apart. With this in mind, examine the list below. If scientists were to break apart each of the items on the list, which items would still be classified in the same way? Which items would be classified differently?
• atoms
• elements
• compounds
• molecules
• matter

Answer 1

Answer:

Compound.

Explanation:

A compound is a made up of two or more than two different elements. It can be broken down into smaller molecules.Elements are combined to form a compound by chemical bonding like ionic bonding and covalent bonding.

Different compounds of different elements can be broken down into the chemical reaction called decomposition reaction. For example:

Using electrolysis, we can break down water into its elements hydrogen and oxygen.    

Answer 2

The answer is a compound because it is only a compound that can be broken to elements. for eg. H2o is a compound and be broken to element of 2 molecules of hydrogen and oxygen
