ROWS in the Periodic Table Periodic recurrence of similar
properties; Trending Solids to liquids to gases Losing electrons to gaining
electrons Etc.
Periods

Because… Down a group
Each row adds another energy level (orbit / shell) – so the outermost electron is farther from the nucleus And the atom gets bigger
Across a period The number of protons increases,
so the increasing positive charge holds the electrons more tightly
And since the energy level of the outermost electron is the same, the atom gets smaller
