Term
| RELATIONSHIP AMONG BOND ORDER, BOND LENGTH, AND BOND ENERGY. |
|
Definition
For a given pair of atoms, a HIGHER bond order results in a SHORTER bond length and a HIGHER bond energy
SHORTER BOND = STRONGER BOND |
|
|
Term
| COMPARING BOND LENGTH AND BOND STRENGTH |
|
Definition
Bond length INCREASES and bond strength DECREASES as the halogen's atomic radius INCREASES.
ATOMIC SIZE INCREASES DOWN A GROUP. |

Term
|
Definition
Generally INCREASES UP a group and ACROSS a period.
NONMETALS ARE MORE ELECTRONEGATIVE AND METALS. |

Term
| Change/Difference in EN and IONIC CHARACTER (relationship) |
|
Definition
>1.7 mostly ionic
0.4-1.7 polar covalent
<0.4 mostly covalent
0 nonpolar covalent |
|
|
Term
| RELATIONSHIP of PERCENT IONIC CHARACTER and DIFFERENCE IN EN |
|
Definition
| Percent ionic character generally increases with DIFFERENCE in EN |
|
|
Term
|
Definition
| as DIFFERENCE IN EN becomes smaller, the bond becomes MORE COVALENT |
