- Step 1: Understand what the periodic table is. It is a chart that organizes all known chemical elements based on their properties.
- Step 2: Learn about groups in the periodic table. Groups are the vertical columns in the table.
- Step 3: Know that elements in the same group share similar characteristics. This is because they have the same number of valence electrons.
- Step 4: Valence electrons are the electrons in the outermost shell of an atom and are important for chemical reactions.
- Step 5: Conclude that the statement about elements in the same group having similar chemical properties is true.
