Elements in a ..................have similar chemical properties.  

• period
• group
• row

The tendency of an atom to attract a shared pair of electrons

• Atomic Radii

• Ionization Energy

• Electronegativity

• Electron Afinity

• Oxidation Number

The most important measurement when you measure the atomic size

• Atomic Radius

• Ionization Energy

• Electronegativity

• Electron Afinity

• Oxidation Number

Atomic radii trends is . . . .

• generally decrease along each period of the table, and increase down each group.

• generally increase along each period of the table, and increase down each group.

• generally increase along each period of the table, and decrease down each group.

• generally decrease along each period of the table, and decrease down each group.
