In the modern Periodic Table ;- #1 ; Groups are the columns down. #2 ; Periods are the lines across.
Alkali metals, alkaline earth metals, transition metals
groups are the vertical columns on the periodic table
The periodic table is arranged from left to right in the order of atomic numbers.
The periodic table has 7 periods and 18 groups. The order of elements is governed by the number of protons.
In the modern Periodic Table ;- #1 ; Groups are the columns down. #2 ; Periods are the lines across.
The 3 major groups are: # Metals - Groups 1-15 and the Inner Transitional Elements # Nonmetals - Groups 1 and 14-18 # Metalloids - Groups 13-17 (Diagonal strip of elements separating the metals from the nonmetals)
