6.2-Classifying the Elements - 2

Elements can be sorted into noble gases, representative elements, transition metals, or inner transition metals based on their:

• Atomic mass

• Atomic number

• Electron configurations

• Melting points

What are the elements of Group 8A commonly known as?

• Halogens

• Alkali metals

• Noble gases

• Alkaline Earth metals

Which statement best describes the noble gases?
