Answer the following question given this paragraph: All the atoms of a given element have the same number of protons in their nucleus, but they may have different numbers of neutrons. Atoms of the same element with different numbers of neutrons are called isotopes. Many elements have one or more isotopes that are radioactive. These isotopes are called radioisotopes . Their nuclei are unstable, so they break down, or decay, and emit radiation. Q: All the atoms of a given element have the same number of what in their nucleus, though they may have different numbers of neutrons? A:

OPTIONS:
- molecules
- electrons
- compounds
- protons

Answer: protons

Answer the following question given this paragraph: Entropy increases as temperature increases. An increase in temperature means that the particles of the substance have greater kinetic energy. The faster moving particles have more disorder than particles that are moving more slowly at a lower temperature. Q: What does increased temperature do to a substance's kinetic energy? A:
OPTIONS:
- generates
- nothing
- decreases
- increases
increases

Answer the following question given this paragraph: A solution is a mixture of two or more substances in which dissolved particles are distributed evenly throughout the solution. The substance that dissolves in a solution is called the solute, and the substance that does the dissolving is called the solvent. The concentration of a solution is the amount of solute in a given amount of solution. A solution with a lot of dissolved solute has a high concentration and is called a concentrated solution. A solution with little dissolved solute has a low concentration and is called a dilute solution. Q: What do you call a mixture of two or more substances in which dissolved particles are distributed evenly throughout? A:
OPTIONS:
- concentrate
- liquid
- water
- solution

Answer: solution
