What family is this?

Boron family

What family is this?

Carbon family

What family is this?

Nitrogen family

What family is this?

Oxygen family (chalogens)

What family is this?

Halogens (Halides)

What family is this?

Noble gases

the quantity of energy required to remove an electron from a gaseous atom or an ion

• increases as you go across P.T. (left to right) (requires more energy to remove an electron)

• decreases as you go down P.T. (top to bottom) (requires less energy to remove an electron from an atom)

Most reactive

• metals: far left bottom (Fr)

• Lowest ionization energy (easily loses electron)

• nonmetals: far right top (F)
  Highest ionization energy (very difficult to lose electron/ "wants" to gain one)

Ionization energy

What trend is this

Ionization energy

• decreases as you go across P.T. (left to right)

More protons to hang onto those electrons as you go left to right (so it gets smaller)

• increases as you go down P.T. (top to bottom)

Less protons to hold onto electrons (atom expands in size)

Ion Size (what is an ion?)

• cations (paws-itive) are smaller than parent atom

• anions are larger than parent atom

Atomic radii

Why trend is this?

Atomic radii

the tendency of an atom in a molecule to attract shared electrons to itself

increases as you go across P.T.

• Remember Fluorine? Highly electronegative, wants to gain electrons

decreases as you go down P.T.

• Remember Francium? Lowest electronegativity

electronegativity

What trend is this?

Electronegativity
