Understand that the periodic table is organized to reflect recurring chemical properties of elements.
Recognize that elements arranged in vertical columns share similar chemical properties due to having the same number of valence electrons.
Know that these vertical columns are called 'Groups' in the periodic table.
Differentiate 'Groups' from 'Periods', which are horizontal rows, and from 'Blocks', which refer to sections based on electron subshells (s, p, d, f).
Conclude that the term describing the arrangement of elements with similar chemical properties is 'Group'.
