Periodic Table & Trends | Periods, groups, ionisation energy, atomic radius

Welcome to Day 6 of the 50 Days of Tutelage series. The periodic table is a highly organized map of the elements. This lesson breaks down how an atom's electron setup determines its position on the table, and how its physical and chemical properties change in predictable ways. We walk through the core concepts in a simple, step-by-step flow: • Rows and Columns: How rows (periods) show the number of electron shells, and columns (groups) show the number of outer electrons and shared traits. • Atomic Size: Why atoms get smaller as you move from left to right across a row, and larger as you move down a column. • Pulling and Removing Electrons: How the energy needed to remove an electron (ionization energy) changes based on how close the electrons are to the nucleus. • Bonding Power: How strongly an atom attracts shared electrons (electronegativity), which decides how elements react and bond with each other. #Chemistry #PeriodicTable #PeriodicTrends #InorganicChemistry #STEM #50DaysOfTutelage
