- This point belongs to The periodic table, especially Development of the periodic table.
- You need to be able to explain how discovery of predicted elements supported Mendeleev's table.
- The key ideas to know are predicted elements and Mendeleev.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Development of the periodic table to exam-style questions, flashcards, and revision notes for The periodic table.
Quick student answer
How do you explain discovery of predicted elements supported Mendeleev's table?
Direct answer
In Chemistry, this page helps you answer questions about discovery of predicted elements supported Mendeleev's table within The periodic table. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are Mendeleev and predicted elements.
Key terms
- Mendeleev: A chemist who developed the periodic table and rearranged elements based on their chemical properties.
- predicted elements: Elements that were forecasted by Mendeleev based on gaps in his periodic table, which were later discovered.
Common trap
Misunderstanding Mendeleev's Predictions: Emphasize that Mendeleev used observed chemical properties to predict the existence and properties of undiscovered elements, which later supported his periodic table.
