Bonding Flashcards
Refers to the bonding force that holds together the constituent atoms in a molecule
Chemical bond
- Formed when two atoms participating in bond formation share equally their electrons to produce a molecule of an element or compound
- Usually involves TWO NON-METAL
Covalent bond
Formed when sharing takes place between the atoms of different electronegativities, between dissimilar atoms during bond formation
Polar bond
Formed when sharing takes place between the atoms of same electronegativity, between similar atoms during bond formation
Nonpolar bond
- Results from the attraction of two opposite chatged particles
- involves a METAL and a NONMETAL
- there is a complete transfer of e- between atoms
Ionic bond
Thermochemical cycle used to determine the lattice energy of ionic compounds
Born-Haber cycle
Occurs if the pair of e- shared are contributed by one atom only
Coordinate covalency
- There are different terminal atoms
* There are lone pairs around the central
Polar molecule
Bskan mag true ang isa ka statement, automatic Polar
Is the distance between the nuclei of the atoms forming the bond
Bond length
True or False
For the same two atoms:
- triple bonds are shorter than double bonds which in turn, are shorter than the single bonds
True
Pertains to single bond, double bond, triple bond and those intermediate between single and double bonds, etc
Bond order
True or False
The higher the bond order, the stabler is the molecules
True
True or False
Bond order zero and negative indicates the molecule does not form or exist
TRUE
Is the amount of energy involved in the formation and breaking of a bond
Bond energy
The formation of a bond is due to the overlap of two atomic orbitals
Valence bond theory
