12. Label and color code YOUR Periodic Table!!
a. Label groups (columns) 1-18 and
periods (rows) 1-7, 6 and 7 on your Periodic Table. Ask your teacher if you need help before you
do this!
b. On your Periodic Table, color and
label the 10 element groups shown on the web site. Be sure to create a ‘key’ so
you know which color represents which group!!
HINT: if you place your mouse over a group name, the elements in
that group will be highlighted for you!
