Verified step by step guidance1
Understand the layout of the periodic table: it is organized in rows and columns.
Recognize that a 'period' refers to a horizontal row of elements across the periodic table.
Know that a 'group' refers to a vertical column of elements down the periodic table.
Recall that elements in the same group share similar chemical properties due to having the same number of valence electrons.
Note that periods represent elements with increasing atomic number from left to right, but do not necessarily share similar chemical properties.
