How many groups are there in the periodic table? How are they labeled?
Verified step by step guidance1
Step 1: Understand that the periodic table is organized into vertical columns known as groups or families.
Step 2: Recognize that there are 18 groups in the periodic table, each with unique properties and characteristics.
Step 3: Note that groups are labeled from 1 to 18, starting from the leftmost column to the rightmost column.
Step 4: Be aware that in addition to numerical labels, groups can also have specific names, such as the alkali metals (Group 1) and the noble gases (Group 18).
Step 5: Remember that elements within the same group typically have similar chemical properties due to having the same number of valence electrons.
