Periodic Table Quiz

Tennessine is classified as a synthetic element because it is:

• Naturally occurring

• Stable

• Artificially produced in a laboratory

• Found in abundance in nature

Which of the following statements about astatine is true?

• It is a stable element with no isotopes.

• It is highly abundant in the Earth's crust.

• It is a non-metal.

• It is highly radioactive.

Synthetic elements are typically produced in:

• Nuclear reactors

• Chemical laboratories

• Particle accelerators

• Fusion reactors

Who is credited with the initial development of the periodic table?

• Dmitri Mendeleev

• Henry Moseley

• Antoine Lavoisier

• Marie Curie

Mendeleev's periodic table was organized based on:

• Atomic number

• Atomic mass

• Atomic radius

• Electron configuration

Henry Moseley's contribution to the periodic table involved:

• Discovering the existence of isotopes

• Arranging elements based on increasing atomic number

• Developing the concept of electron shells

• Identifying the noble gases

Mendeleev's periodic table left gaps for elements that were not yet discovered. These gaps were later filled as predicted by:

• Dalton's atomic theory

• Avogadro's law

• Mendeleev's periodic law

• Moseley's atomic theory

Moseley's discovery led to the realization that:

• Elements in the same column share similar properties

• Elements in the same row have similar properties

• Atomic mass is the most crucial factor in element classification

• Atomic number determines an element's properties

What did Moseley's discovery lead to the realization of?

• Elements in the same column share similar properties

• Elements in the same row have similar properties

• Atomic mass is the most crucial factor in element classification

• Atomic number determines an element's properties

Whose periodic table left gaps for elements that were not yet discovered and later filled as predicted?

• Dalton's atomic theory

• Avogadro's law

• Mendeleev's periodic law

• Moseley's atomic theory
