Periodic Table & Periodic Trends Unit Review

Who is attributed with the idea of arranging the known elements of his time in a table according to their chemical and physical properties?

• Marie Curie
• Dmitri Mendeleev
• Isaac Newton
• Albert Einstein

This scientist who arranged the periodic table also predicted that the empty spaces on his periodic table represented

• a) radioactive elements.

• b) isotopes.

• undiscovered elements

• ions

Who arranged the periodic table of elements in the order of ATOMIC NUMBER?

• Albert Einstein
• Marie Curie
• Dmitri Mendeleev
• Henry Moseley

The periodic law states there is a periodic repetition of physical and chemical properties of the elements

• a) when they are arranged in order of increasing atomic radii.

• b) if only nonmetals are considered.

• c) when they are arranged in order of increasing atomic mass.

• d) when they are arranged in order of increasing atomic number.

The vertical columns of the periodic table are called

• rows
• groups or families
• elements
• periods

Each period in the periodic table corresponds to electron

• sublevels

• atomic mass

• energy levels

• atomic numbers
