Question
Explain how the group in which an element is located relates to the number of valence electrons in its outer shell.
Solution
The group number of an element in the periodic table corresponds to the number of valence electrons in its outer shell.
Step 1: Understanding the Periodic Table The periodic table is organized into groups (columns) and periods (rows). The groups are numbered from 1 to 18 from left to right.
Step 2: Understanding Valence Electrons Valence electrons are the electrons in the outermost shell of an atom. These electrons play a key role in chemical reactions and bonding.
Step 3: Relating Group Number to Valence Electrons For elements in groups 1 and 2, the
