d and f BLOCK ELEMENTS

According to the text, what is the significance of being able to name elements with Z>100?

• It proves they are found in nature
• It allows for easier memorization
• It follows IUPAC nomenclature for systematically naming newly discovered elements
• It determines their stability

What historical aspect of the Periodic Table is explicitly mentioned as a study topic in this unit?

• Its invention by a single scientist
• Its rejection by the scientific community
• Its historical development
• Its use in ancient civilizations

What does the text state about the continuation of element synthesis efforts?

• Efforts stopped after element 100
• Efforts are only focused on finding elements in space
• Efforts to synthesise new elements are continuing
• Only natural elements are being sought

Which of the following is a specific property trend mentioned that students should recognize?

• Density
• Solubility
• Atomic/ionic radii
• Boiling point

Why is studying the electronic configuration of atoms important in the context of this unit?

• It determines the color of elements
• It is the basis for understanding periodic classification and trends
• It is only relevant for transition metals
• It helps in calculating atomic weight
