PERIODICITY

ATOMIC RADII

• The atomic radii is half the distance of the diameter of an atom.
• The radii of the circles get larger as you go further down and to the left of the periodic table.

IONIC RADII

• The ionic radii is half of the diameter of an ion and is smaller than the atomic radii.
• The radii of the circles also get larger as you go further down and to the left of the periodic table.

ELECTRONEGATIVITY

• Electronegativity is the likeliness of an atom attracting a bonding pair of electrons.
• The further right and higher you go on the periodic table the higher the electronegativity will be.

IONIZATION ENERGY

• Ionization is the amount of energy it takes to change an atom or molecule into an ion.
• The higher up and further right you go on the periodic table the more the ionization energy increases.

VALENCE ELECTRON

• An electron that's on the outer most shell and can be transferred or shared with other atoms
• The further you go down the periodic table the more valence electrons an atom will have.

LATTICE ENERGY

• The energy given off when oppositely charged ions in the gas phase come together to form a solid.
• The more you go down a group the more the lattice energy decreases
