Nova Hunting the Elements Worksheet Answers
Nova’s “Hunting the Elements” is a fascinating documentary that explores the periodic table and the elements that make up our world. If you’re looking for answers to the worksheet that accompanies this documentary, you’re in the right place.
Part 1: Multiple Choice Questions
- What is the primary reason why elements are arranged in a periodic table? a) To list elements in alphabetical order b) To group elements by their physical properties c) To organize elements by their atomic number d) To separate metals from non-metals
Answer: c) To organize elements by their atomic number
- Which of the following elements is a noble gas? a) Carbon b) Oxygen c) Neon d) Nitrogen
Answer: c) Neon
- What is the term for the horizontal rows of elements in the periodic table? a) Periods b) Groups c) Blocks d) Families
Answer: a) Periods
Part 2: Short Answer Questions
- What is the atomic number of an element, and how is it used in the periodic table?
Answer: The atomic number of an element is the number of protons present in the nucleus of an atom. It is used in the periodic table to organize elements in order of increasing atomic number.
- Describe the difference between a metal and a non-metal.
Answer: Metals are typically shiny, malleable, and good conductors of electricity. Non-metals, on the other hand, are dull, brittle, and poor conductors of electricity.
Part 3: Essay Questions
- Explain the significance of the periodic table in understanding the properties of elements.
Answer: The periodic table is a powerful tool for understanding the properties of elements. By organizing elements in a logical and systematic way, the periodic table allows us to identify patterns and relationships between elements. This, in turn, helps us to predict the properties of elements, such as their reactivity, electronegativity, and physical properties.
- Discuss the role of Dmitri Mendeleev in the development of the periodic table.
Answer: Dmitri Mendeleev was a Russian chemist who played a crucial role in the development of the periodic table. In 1869, Mendeleev published a periodic table that arranged elements in order of increasing atomic weight. He also predicted the existence of undiscovered elements and left gaps in the table for them. Mendeleev’s work laid the foundation for the modern periodic table, which is still widely used today.
Notes
📝 Note: The atomic number of an element is a unique identifier that distinguishes it from other elements. It is used in the periodic table to organize elements in order of increasing atomic number.
📝 Note: The periodic table is a dynamic tool that has evolved over time. It has undergone many changes and updates, and new elements have been added to the table as they have been discovered.
Conclusion
Nova’s “Hunting the Elements” is a fascinating documentary that explores the periodic table and the elements that make up our world. By understanding the properties and relationships between elements, we can gain a deeper appreciation for the natural world and the role that elements play in our daily lives.
