Electron Shielding
|
The reduction in the attractive force between a positively charged nucleus and its outermost electrons due to the cancellation of some of the positive charge by the the negative charges of the inner electrons
Increases as you move down Stays the same as you move across |
|
|
Atomic Radius
|
The distance between the edge of an atom of which the electron cloud ends to the nucleus of the two bonding atoms and divided by two
Increases as you go down Decreases from left to right |
|
|
Ionization Energy
|
The energy required to remove one e- from a neutral atom of an element.
Decreases as you go down Increases from left to right. |
|
|
Electronegativity
|
The measure of an atom in a chemical compound to attract electrons
Decreases as you go down Increases as you go across |
|
|
Melting Point
|
In order to melt a substance, heat is added which speeds up vibration to the point where the atoms are no longer locked in place
Decreases as you go down Peaks twice as you go across. Once in the middle of the D-Block and again in the middle of the P-Block |
|
|
Boiling point
|
In order to boil a substance, heat is added which speeds up vibration to the point where the atoms are no longer locked in place
Decreases as you go down Peaks twice as you go across. Once in the middle of the D-Block and again in the middle of the P-Block |
|
|
Ion
|
An atom or molecule with a net electric charge due to the loss or gain of one or more electrons
|
|
|
Bond Radius
|
The distance from the atomic nucleus to the outermost stable electron orbital in an atom at equilibrium divided by two
