REVIEW OF FUNDAMENTAL CONCEPTS Flashcards
Atomic theory of matter that states that atom is invidivisible
Dalton’s Atomic Theory
He created the nuclear model of atom that looks like a plumpudding/watermelon model
J.J. Thomson
He, along with others, used a tin foil of gold for a nuclear model of an atom.
Ernest Rutherford
same atomic number, different mass number
isotopes
they distinguish atomic orbitals
Quantum numbers
quantum number that represents the orbital size and energy level
principal quantum number
quantum number that describes the orbital shape (sublevels/subshells)
Secondary quntum number
describes the orbital orientation
magnetic quantum number
describes the electron spin direction
Spin quantum number
It refers to the formation of a chemical bond between two or more atoms.
Chemical Bonding
a type of chemical bonding which involves transfer of electrons from one molecules to another
ionic bonding
sharing of electrons
covalent bonding
a covalent bond with atoms having unequal attarction for electrons so the sharing is unequal.
polar bonds
distribution of electrons
Electron configuration
concept of mixing 2 atomic orbitals with the same energy levels.
hybridization
