Exploring the Periodic Table

Who is known as the father of the periodic table?

• Isaac Newton

• Dmitri Mendeleev

• Marie Curie

• Albert Einstein

What year did Mendeleev publish his first periodic table?

• 1875

• 1886

• 1869

• 1901

What is Mendeleev's periodic law?

• Mendeleev's periodic law states that elements are arranged by their color.

• Mendeleev's periodic law states that the properties of elements are a periodic function of their atomic weights.

• Mendeleev's periodic law indicates that elements have no relation to their atomic weights.

• Mendeleev's periodic law claims that the properties of elements are random and do not follow any pattern.

How did Mendeleev arrange the elements in his periodic table?

• By decreasing atomic mass and grouping by color.

• By random arrangement without any specific criteria.

• By increasing atomic number and ignoring properties.

• By increasing atomic mass and grouping by similar properties.

What was a significant prediction made by Mendeleev?

• The prediction of the existence of gallium.

• The prediction of the existence of helium.

• The prediction of the existence of neon.

• The prediction of the existence of argon.

What is the modern periodic table based on?

• The mass of elements.

• The atomic number of elements.

• The chemical properties of elements.

• The color of elements.

How are elements classified in the modern periodic table?

• Elements are grouped by their year of discovery.

• Elements are classified by atomic number and grouped by similar chemical properties.

• Elements are classified by color and size.

• Elements are classified based on their physical state at room temperature.

What are the main categories of elements in the periodic table?

• Metals, Nonmetals, Metalloids, Alkali Metals, Alkaline Earth Metals, Transition Metals, Lanthanides, Actinides, Halogens, Noble Gases

• Synthetic Elements

• Organic Compounds

• Noble Liquids

What is the significance of atomic number in the periodic table?

• The atomic number determines the color of the element.

• The atomic number indicates the mass of the element.

• The atomic number is significant because it defines the element and its properties.

• The atomic number is irrelevant to chemical reactions.

How does the periodic table reflect the periodicity of elements?

• The periodic table is a historical document with no scientific relevance.

• The periodic table only categorizes elements by their mass.

• The periodic table reflects the periodicity of elements by organizing them in a way that shows recurring trends in their properties based on atomic structure.

• The periodic table lists elements randomly without any trends.
