GENERAL CHEMISTRY EXAM STUDY GUIDE 1
1. Isotope ANS Different number of neutrons. Same atomic number but different
Mass numbers
2. Atomic Number ANS (Z) number of protons
3. Mass Number ANS Sum of protons and neutrons
4. How many isotopes are there for Hydrogen ANS three
5. protium ANS isotope of hydrogen (1+)
6. deuterium :isotope of hydrogen ANS one proton and one neutron (D)
7. tritium :isotope of hydrogen ANS one proton and two neutrons (T)
8. ion ANS atom or molecule carrying a charge
9. A Wave Function: describes an orbital ANS the shape and volume of space where
an electron can be found
10. Orbital ANS A region of space where the probability of finding an electron is 90%
(construct)
11. Degenerate Orbitals ANS Orbitals of the same energy
12. magnetic quantum number ANS spatial orientation of an orbital (-l, +l, 0)
, GENERAL CHEMISTRY EXAM STUDY GUIDE 1
13. Spin Quantum Number ANS rotation of electron about it's axis (+1/2, -1/2)
14. Aufbau Principal atomic orbitals are filled in order of increasing energies (lowest
energy orbital up)
15. Pauli Exclusion Principal ANS orbital can accommodate two electrons with
opposite spins
16. Hund's Rule ANS "maximum multiplicity" orbitals of the same energy will arrange
themselves so the electrons that occupy them will have the greatest number of
parallel spins
17. Which group has the most stable electronic configuration ANS noble gases 'octet'
18. Two forms of chemical bonding ANS covalent and ionic
19. ionic bond ANS transfer of electrons from one atom to another
20. electropositive ANS low tendency to attract shared electrons
21. electronegative ANS high tendency to attract shared electrons
22. Covalent Bond ANS sharing of electrons between atoms
