A horizontal row of elements in the periodic table.

• column
• group
• period

Elements in a ..................have similar chemical properties.  

• period
• group
• row

The elements on the right of the zigzag line are:

• metals

• noble gases

An element's identity is determined by the number of

• electrons.
• protons.
• neutrons.
• valence.
