Periodic Trends Concepts
Periodic trends are the predictable changes in the properties of elements as their atomic number increases. These trends can be observed in a variety of atomic properties, including atomic radius, ionization energy, electronegativity, and electron affinity.
Atomic radiusis the distance from the nucleus to the outermost electron shell. In general, atomic radius decreases from left to right across a period and increases from top to bottom down a group.
Ionization energyis the energy required to remove an electron from an atom. In general, ionization energy increases from left to right across a period and decreases from top to bottom down a group.
Electronegativityis the ability of an atom to attract electrons. In general, electronegativity increases from left to right across a period and decreases from top to bottom down a group.
Electron affinityis the energy released when an electron is added to an atom. In general, electron affinity increases from left to right across a period and decreases from top to bottom down a group.
