Transcript
Metal, Nonmetals, Metalloids
Think inside the box
• Name
– Duh. It tells you what
element it is.
• Chemical Symbol
– Shorthand way of writing
element
• Atomic Number
– Protons in Nucleus
• Atomic Mass
– Protons + Neutrons in
Nucleus
Arrangement of the Periodic Table
Groups or Families
• Vertical columns
Periods
• Horizontal columns
• Elements have similar
chemical properties
• Atomic number increases
from left to right.
• What gives atoms/elements
their chemical properties?
• The Period an element is in
determines the number of
“race tracks” for the
electrons of the atom.
