Higher densities
Higher atomic masses
Higher atomic numbers
Higher atomic radii
Answer is Right!
Answer is Wrong!
The correct answer is: A. Higher densities.
Heavy metals are metals that have a high density. This means that they have a lot of mass for their size. Heavy metals are often used in industrial applications because they are strong and durable. They can also be toxic, so it is important to handle them with care.
Here is a brief explanation of each option:
- Option B: Higher atomic masses. Atomic mass is the total mass of an atom, which is determined by the number of protons and neutrons in its nucleus. Heavy metals do not necessarily have higher atomic masses than other atoms. For example, hydrogen has an atomic mass of 1, while lead has an atomic mass of 207.
- Option C: Higher atomic numbers. Atomic number is the number of protons in an atom’s nucleus. Heavy metals do not necessarily have higher atomic numbers than other atoms. For example, hydrogen has an atomic number of 1, while lead has an atomic number of 82.
- Option D: Higher atomic radii. Atomic radius is the radius of an atom’s nucleus. Heavy metals do not necessarily have higher atomic radii than other atoms. For example, hydrogen has an atomic radius of 0.0529 nanometers, while lead has an atomic radius of 1.75 nanometers.
