Chemistry Chapter 5 Review

The idea of arranging the elements in the periodic table according to their chemical and physical properties is attributed to whom?

• Dmitri Mendeleev

• Antoine Lavoisier

• Marie Curie

Mendeleev predicted that the spaces in his periodic table represented

• metals

• Unknown elements

• elements with a low atomic number

Evidence gathered since Mendeleev's time indicates that a better arrangement than atomic mass for elements in the periodic table is an arrangement by

• alphabetical

• color

• Atomic number

The discovery of what elements added a new column to Mendeleev's periodic table?

• noble gasses

• metals

• nonmetals

What are the radioactive elements with atomic numbers from 90 to 103 called?

• Actinides

• Lanthanides

• Noble Gasses

What are the elements with atomic numbers from 58 to 71 called?

• Actinides

• Lanthanides

• Noble Gasses

Argon, krypton, and xenon below to which group?

• 18

• 15

• 2

The periodic law states that the properties of elements are periodic functions of their atomic numbers. What determines the position of each element in the periodic table?

• group number

• number of protons in their nuclei

• number of electrons in their nuclei

The periodic law allows some properties of an element to be predicted based on its

• group number

• number of protons in their nuclei

• number of electrons in their nuclei

Elements in a group or column in the periodic table can be expected to have similar

• number of neutrons

• properties

• chemical symbol
