Episode notes
Dalton's Atomic Theory
- John Dalton, an English school teacher, proposed modern atomic theory in 1804.
- He suggested that elements are made of indestructible atoms, each with a unique mass, and tried organizing them by weight.
The Search for Patterns
- Scientists looked for patterns in elements, even manipulating them.
- This drive led to the concept of periodicity, where element properties repeat based on their arrangement.
Mendeleev's Periodic Table
- Dmitri Mendeleev created the modern periodic table in 1869 while writing a chemistry textbook.
- He organized elements by properties and atomic weight, leaving gaps for undiscovered elements.
