Along a period, electronegativity tends to increase due to the higher effective nuclear charge and the reduced atomic size.
Electronegativity Increases Along a PeriodĮlectronegativity is the measure of an atom’s ability to attract electrons in a chemical bond. This trend can be attributed to the increasing effective nuclear charge, which pulls the outermost electrons closer to the nucleus, resulting in a smaller atomic radius. Atomic Size Decreases Across a PeriodĪs you move from left to right across a period in the periodic table, the atomic size of elements decreases. This arrangement allows scientists to easily identify trends and relationships between elements. It is a meticulously organized masterpiece that arranges elements in order of increasing atomic number and groups them based on their similar properties. The periodic table is more than just a jumble of elements.
The Periodic Table is a Masterpiece of Organization
