Electronegativity:The Oxygen Family

  • the electronegativity trends apply
  • oxygen family
  • group 16 elements are highly electronegative due to the fact that they need only need to attract 2 bonding electrons to satisfy the octet rule
  • electronegativity decreases within the group because of increment of atomic radii
  • Sulfur electronegativity: 2.6

Ionization Energy

  • the amount of energy needed to move electrons from the valence shell to an isolated neutral atom
  • increases from left to right, within the period
  • decreases from top to bottom within a group

  • the ability for an atom to attract bonding electrons to its valence level to satisfy the octet rule
  • increases from left to right in a period
  • from the bottom to the top within a group

Activity Series

Electron Affinity: The Oxygen Family

  • sulfur's electron affinity is 200kJ/mol
  • Below sulfur is Selenium which has an electron affinity of 195kJ/mol

  • the change in energy in (kJ/mole) of a neutral atom when an electron is added to the atom to form a negative ion
  • a neutral atom's likelihood of gaining an electron
  • decreases as its atomic weight increases

Group 16

  • Group 16: oxygen family within the periodic table
  • consists of oxygen, sulfur, selenium, tellurium, and polonium

  • used to predict products in displacement reactions and reactivity of metals with water and acids in replacement reactions
  • used to predict the products in reactions involving a different metal during a single or double replacement reaction
  • it increases as you move down the family
  • it will increase as you travel left to right in a period
  • activity series only applies to metals, with the exceptions of carbon, hydrogen, and sometimes the halogens
  • no elements within group 16 are on the activity series table
  • ionization energy decreases within the family
  • group 16 shows less ionization energy than group 15
  • due to group 15 elements having a different valence shell configuration, making them more symmetrical and stable than the oxygen family
  • Sulfur Ionization Energy: 1000 kJ/mole
