Physical Science - Periodic Table and Trends

In the modern periodic table elements are arranged by:

• atomic mass
• atomic number
• valence electrons
• number of isotopes

Each row in the periodic table is called a 

• group
• period
• cluster
• unit

Each column in the periodic table is called a 

• period
• group
• cluster
• unit
