Periodic Table Insights

Who is credited with the discovery of the periodic table?

• Albert Einstein

• Isaac Newton

• Dmitri Mendeleev

• Marie Curie

What are some merits of the long form of the periodic table?

• The long form of the periodic table is outdated and irrelevant

• The merits of the long form of the periodic table include providing a comprehensive view of all known elements and facilitating the identification of trends and patterns in element properties.

• There are fewer elements included in the long form, limiting its usefulness

• It is harder to navigate and understand compared to the short form

What was the historical development that led to the creation of the periodic table?

• Invention of the electron microscope

• Discovery of the atomic theory by John Dalton

• Creation of the first synthetic element

• Discovery of the periodic law by Dmitri Mendeleev

What is Mendeleev's contribution to the periodic table?

• Mendeleev created the first widely-accepted periodic table of elements.

• Mendeleev invented the concept of elements

• Mendeleev discovered the periodic table

• Mendeleev organized the periodic table by atomic number

How are groups and periods arranged in the periodic table?

• Groups are arranged vertically, and periods are arranged horizontally.

• Groups are arranged in a zig-zag pattern, and periods are arranged in a spiral.

• Groups are arranged in a circular pattern, and periods are arranged diagonally.

• Groups are arranged horizontally, and periods are arranged vertically.

Which group of elements are known as noble gases?

• Group 14 elements

• Group 8 elements

• Group 10 elements

• Group 18 elements

How is the periodic table classified based on its properties?

• By sorting elements alphabetically

• By grouping elements randomly

• By arranging elements in order of increasing atomic number and grouping elements with similar properties into columns called groups or families.

• By arranging elements based on their color

What do the letters s, p, d, and f represent in the periodic table?

• Shapes

• Numbers

• Colors

• Orbital types

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

• The atomic number represents the mass of an atom's nucleus.

• The atomic number indicates the reactivity of an element.

• The atomic number determines the number of electrons in an atom's outer shell.

• The atomic number indicates the number of protons in an atom's nucleus.
