History of the Periodic Table

What was Antoine Lavoisier's contribution to the organization of elements in 1789?

• Introduced modern chemical nomenclature.

• Classified 33 elements based on their chemical properties.

• Proposed the Law of Triads.

• Organized elements by atomic mass.

Which chemist introduced modern chemical nomenclature using symbols based on the initial letters of Latin names?

• Antoine Lavoisier

• Johann Wolfgang Döbereiner

• Jöns Jacob Berzelius

• John Newlands

How did Dmitri Mendeleyev primarily organize the elements in his first periodic table in 1869?

• By their atomic number.

• By their electron configurations.

• By their chemical properties and atomic mass.

• By their physical state at room temperature.

What fundamental discovery did Henry Moseley make in 1913 that led to the modern periodic table?

• Elements should be arranged by atomic mass.

• Elements should be arranged by atomic number.

• Elements could be grouped into triads.

• Elements' properties repeat every eight elements.
