What is the definition and pattern for the following trends?

Atomic Radius

Ionization Energy

Electronegativity

Atomic Radius: distance from the center of the atom to the outermost energy level. Radius increases as you go down a group and decreases as you go across a period.

Ionization Energy: amount of energy to remove an electron. IE decreases as you go down in a group and increases as you go across a period.


Electronegativity: ability to attract electrons when bonded. EN decreases as you go down in a group and increases as you go across a period with the exception of the noble gas group, which don't bond.
