Chemistry Flashcards
Orbitals
Energy shells are broken further into sub shells. Different orbitals such as S,P,D and F orbitals
Electron configuration
Distribution of electrons in an atom or molecule
Spin
Electrons have two possible states. Spin up or spin down.
Ionic bonding
Donating electrons
Electrostatic attraction
Opposite charge on ions bond them together
Giant ionic lattice
Opposite charger sodium chloride ions where ions are arranged in a regular pattern
Covalent bonding
Sharing electrons
Lone pair
A non binding pair of electrons
Organic compound
A compound that contains one or more carbine in a carbon chain
Metallic bonding
Positive ions with a sea of free electrons.
Delocalised electrons
Electrons that are free to move
Electronegativity
The tendency of an atom to attract a bonding pair of electrons
Non-polar molecule
A molecule where the electrons are distributed evenly throughout the molecule.
Polar molecule
A molecule with partial positive charge in one part of the molecule and similar negative charge in another part due to an uneven distribution of electrons
Intermolecular forces
The attraction/repulsion between neighbouring molecules.
Dipole
Separation of charges within a covalent molecule
Van der waals forces
Every intermolecular attractions.
Mole
A unit of substance equivalent to the number of atoms in 12g of carbon 12
Avagadros constant
6.023 X 10(23)
Molar mass
The mass of one mole of a substance
