Periodic Trends
Ionization Energy
:
Decreases down the group because the electron shielding effect becomes less tightly.
Increases across the period because the nuclear charge increases
Definition
: Energy required to remove an electron
Electronegativity
Definition
: ability of an atom to attract and bind with electrons.
Increases across the period because of the increase in nuclear charge.
Decreases down the group because of the increase in the atomic number.
Atomic Radius
Definition
: 1/2 the distance between the nuclei of two identical atoms.
Decreases across the period because of the great attraction of nuclear charge.
Increases down the group because an extra shell is added.
Electron Affinity
Definition
: ability of an atom to accept an electron
Increases from left to right because of the increase in the nuclear charge.
Decreases down the group because the electron shielding effect increases
