Cards

Term
BOND ENERGY
Definition
ENERGY REQUIRED TO BREAK THE BOND
Term
IONIC BONDS
Definition
AN ELECTROSTATIC ATTRACTION BETWEEN IONS; USUALLY PRODUCED BY THE REACTION BETWEEN A METAL AND A NONMETAL.
Term
COVALENT BONDS
Definition
ELECTRONS  ARE SHARED BY NUCLEI
Term
COULOMBS'S LAW
Definition
USED TO CALCULATE THE ENERGY OF AN IONIC BOND
Term
VALENCE ELECTRONS
Definition
OUTERMOST ELECTRON; FOCUS ON NS, NP, AND D ELECTRONS OF TRANSITION ELEMENTS
Term
BOND LENGTH
Definition
THE DISTANCE BETWEEN THE 3 NUCLEI WHERE THE ENERGY IS MINIMUM BETWEEN THE TWO NUCLEI
Term
BOND ORBITAL
Definition
DESCRIBES THE MOTION OF THE 2 ELECTRONS OF OPPOSITE SPINS
Term
LONE PAIR ORBITALS
Definition
THE ORBITALS OF ELECTRONS ON A BOUNDED ATOM THAT ARE DISTORTED AWAY FROM THE BOND REGION ALSO HAVE A NEW DESCRIPTIONS (WAVE LENGTH).
Term
IONIC BOND
Definition
THE BONDING ORBITAL IS STRONGLY DISPLACED TOWARD ONE NUCLEI
Term
COVALENT BOND
Definition
BOND ORBITAL IS MORE OR LESS EVENLY DISTRIBUTED AND THE ELECTRONS ARE SHARED BY TWO ELECTRONS
Term
ELECTRONEGATIVITY
Definition
THE ABILITY OF AN ATOM IN A MOLECULE TO ATTRACT SHARED ELECTRONS TO ITSELF
Term
BOND POLARITY AND ELECTRONEGATIVITY
Definition
DETERMINES POLARITY SINCE IT MEASURES A NUCLEUS ATTRACTION OR PULL ON THE BONDED ELECTRON PAIR
Term
IONIC BONDING
Definition
THE FINAL RESULT OF IONIC BONDING IS A ASOLID, REGULAR ARRAY OF COTIONS AND ANIONS CALLED A CRYSTAL LATTICE. 
Term

BOND TYPES

1 SINGLE

2 DOUBLE

3 TRIPLE

 

Definition

1 ONE PAIR OF ELECTRONS SHARED

2 TWO PAIRS OF ELECTRONS SHARED

3 TRIPLE THREE PAIRS OF ELECTRONS SHARED

Term
COORDINATE COVALENT BONDS
Definition
SOME ATOMS SUCH AS N AND P, TEND TO SHARE A LONE PAIR WITH ANOTHER ATOM THAT IS SHORT OF ELECTRONS, LEADING TO THE FORMATION OF A COORDINATE COVALENT BOND. 
Term
RESONANCE STRUCTURES
Definition
EXPERIMENTS SHOW THAT OZONE, O3 HAS EQUAL BOND LENGHTS AND EQUAL BOND STRENGTHS, IMPLYING THAT THERE IS AN EQUAL NUMBER OF BOND PAIRS ON EACH SIDE OF THE CENTRAL O ATOM.
Term
BOND ORDER
Definition
SIMPLY THE NUMBER OF BONDING ELECTRON PAIRS SHARED BY TWO ATOMS IN A MOLECULE.
Term
BOND LENGTH
Definition
DISTANCE BETWEEN THE NUCLEI OF TWO BONDED ATOMS
Term
BOND ENERGY
Definition
THE GREATER THE # OF ELECTRON PAIRS BETWEEN A PAIR OF ATOMS, THE SHORTER THE BOND.
Term
BOND DISSOCIATION ENERGY
Definition
GASEOUS ATOM; E SUPPLIED TO BREAK A CHEMICAL BOND
Term
FORMAL CHARGE
Definition
THE DIFFERENCE BETWEEN THE # of valence electrons on the free element and the # OF ELECTRONS ASSIGNES TO THE ATOM IN THE MOLECULE
Term
DIPOLE MOMENT
Definition
SEPARATION OF THE CHARGE IN A MOLECULE; PRODUCTS OF THE SIZE OF THE CHARGE AND THE DISTANCE OF SEPARATION.
