PERIODIC TABLE TREND

ATOMIC RADII

• Distance between the 2 nuclei halved in half
• As it moves left to right it decreases
• As it moves down the columns it increases

Untitled Slide

IONIC RADII

• Radius of atoms ion
• Negative ions bigger than atom
• As an ion becomes a cation it becomes smaller

Untitled Slide

ELECTRONEGATIVITY

• Property that describes the ability of atom to attract electrons
• Increases left to right
• Decreases going up to down

Untitled Slide

IONIZATION ENERGY

• Energy necessary to remove electron from the neutral atom
• Left to right it increases
• Moving down it decreases

Untitled Slide

MELTING POINT TRENDS

• amount of energy required to break a bond(s) to change the solid phase of a substance to a liquid.
• Metals Possess high melting point
• Non metals possess low melting point

Untitled Slide

METALLIC CHARACTER

• How readily an atom can lose an electron
• Increase left to right
• Decrease down the group
