Where are the metals?
On the periodic table, metals are located to the left and toward the center, separated from the nonmetals by a “staircase” or zig-zag line. About 75% of the elements are metals
Where are the non-metals?
the staircase, or more to the right
Where are the Metalloids?
Metalloids are found along the staircase-shaped line that separates the metals from the nonmetals on the periodic table. on the staircase. like the steps of the stair case.
Where are the Staircase?
The “staircase” on the periodic table is a bold, zig-zagging line that separates the metals from the nonmetals.
Know the group names and where they are located on the periodic table
Alkali metals group 1, alkaline earth metals group 2, halogens group 7, noble gasses group 8
What is the difference between column and period
Column (Group): Up and down — elements have similar properties.
Period (Row): Left to right — elements have different properties.
