Matter And Materials Flashcards
Define bond energy
The energy required to break a particular bond in a compound
What is an orbital
A region of space around the nucleus where electrons are most likely to be found
What is a chemical bond
An electrostatic force holding atoms together in a molecule or crystal
What does VSEPR stand for
Valence shell electron pair repulsion
Define electronegativity
A measure of how strongly and atom attracts the shared pair of electrons in a chemical bond
What is a polar bond
A covalent bond in which electrons are pulled closer to the atom with the higher EN
What is a dipole
A molecule with a + and - spend as a result of a polar bond
Define bond length
The distance between the nucleus of the covalently bonded atoms
Define bond energy
The amount of energy required to break one mole of a particular covalent bond in the gaseous state
Define bond order
The number of bonds (single, double, triple) that exist between 2 atoms
What is an Interatomic force
An electrostatic force of attraction between atoms due to the sharing or transfer of electrons
What is an intermolecular force
An attraction between molecules
