Study Notes

Atomic Radius

  • Decreases from left to right across a period due to increased nuclear charge and decreased shielding
  • Increases down a group due to increased shielding and decreased nuclear charge
  • Atomic radius is smallest at the top right of the periodic table (fluorine) and largest at the bottom left (cesium)

Electronegativity

  • Increases from left to right across a period due to increased nuclear charge and decreased shielding
  • Decreases down a group due to increased shielding and decreased nuclear charge
  • Electronegativity is highest at the top right of the periodic table (fluorine) and lowest at the bottom left (cesium)

Ionization Energy

  • Increases from left to right across a period due to increased nuclear charge and decreased shielding
  • Decreases down a group due to increased shielding and decreased nuclear charge
  • Ionization energy is highest at the top right of the periodic table (helium) and lowest at the bottom left (cesium)

Electron Affinity

  • Increases from left to right across a period due to increased nuclear charge and decreased shielding
  • Decreases down a group due to increased shielding and decreased nuclear charge
  • Electron affinity is highest at the top right of the periodic table (chlorine) and lowest at the bottom left (cesium)

Metallic Character

  • Decreases from left to right across a period due to increased nuclear charge and decreased shielding
  • Increases down a group due to increased shielding and decreased nuclear charge
  • Metallic character is highest at the bottom left of the periodic table (cesium) and lowest at the top right (fluorine)

Reactivity

  • Increases from left to right across a period due to increased nuclear charge and decreased shielding
  • Decreases down a group due to increased shielding and decreased nuclear charge
  • Reactivity is highest at the top right of the periodic table (fluorine) and lowest at the bottom left (cesium)

Blocks of the Periodic Table

  • s-block: elements in the first two columns of the periodic table, characterized by the filling of the s subshell
  • p-block: elements in the last six columns of the periodic table, characterized by the filling of the p subshell
  • d-block: elements in the middle of the periodic table, characterized by the filling of the d subshell
  • f-block: elements at the bottom of the periodic table, characterized by the filling of the f subshell

Atomic Radius

  • Decreases from left to right across a period due to increased nuclear charge and decreased shielding, resulting in a smaller radius
  • Increases down a group due to increased shielding and decreased nuclear charge, resulting in a larger radius
  • Fluorine has the smallest atomic radius, while cesium has the largest

Electronegativity

  • Increases from left to right across a period due to increased nuclear charge and decreased shielding, making it harder to attract electrons
  • Decreases down a group due to increased shielding and decreased nuclear charge, making it easier to attract electrons
  • Fluorine has the highest electronegativity, while cesium has the lowest

Ionization Energy

  • Increases from left to right across a period due to increased nuclear charge and decreased shielding, making it harder to remove electrons
  • Decreases down a group due to increased shielding and decreased nuclear charge, making it easier to remove electrons
  • Helium has the highest ionization energy, while cesium has the lowest

Electron Affinity

  • Increases from left to right across a period due to increased nuclear charge and decreased shielding, making it easier to gain electrons
  • Decreases down a group due to increased shielding and decreased nuclear charge, making it harder to gain electrons
  • Chlorine has the highest electron affinity, while cesium has the lowest

Metallic Character

  • Decreases from left to right across a period due to increased nuclear charge and decreased shielding, resulting in a less metallic character
  • Increases down a group due to increased shielding and decreased nuclear charge, resulting in a more metallic character
  • Cesium has the highest metallic character, while fluorine has the lowest

Reactivity

  • Increases from left to right across a period due to increased nuclear charge and decreased shielding, making elements more reactive
  • Decreases down a group due to increased shielding and decreased nuclear charge, making elements less reactive
  • Fluorine is the most reactive element, while cesium is the least reactive

Blocks of the Periodic Table

  • s-block: elements in the first two columns, characterized by the filling of the s subshell
  • p-block: elements in the last six columns, characterized by the filling of the p subshell
  • d-block: elements in the middle, characterized by the filling of the d subshell
  • f-block: elements at the bottom, characterized by the filling of the f subshell
