MTL 200 Final Exam UPDATED Exam
Questions and CORRECT Answers
atomic mass vs. atomic weight - CORRECT ANSWER - Mass : the sum of Protons and
Neutrons of the element.
Weight : Weighted avgerage of the isotopes of given element
quantum numbers (name, visual meaning, symbol) - CORRECT ANSWER - Principle :
Shell -- energy level / size (n)
Angular Momentum : Subshell -- cloud shape (l)
Magnetic : Orbital -- cloud shape variant (m_{l})
Spin : Spin -- electron spin (up/down) (m_{s})
subshell letters (in order and shape name) - CORRECT ANSWER - s (sphere), p
(dumbbell), d (pedal), f (double pedal)
how to setup orbital order - CORRECT ANSWER - orbitals in the same column, energy
levels in the same row.
shave off the top corner.
Group 1, Group 2, Group 7, Group 8 electron config values - CORRECT ANSWER - s^1,
s^2, p^5, p^6
monovalent, divalent - CORRECT ANSWER - monovalent: 1 electron needed to gain or
lose to fill valence
divalent: 2 electrons needed to gain or lose to fill valence
, equilibrium spacing - CORRECT ANSWER - distance between two atoms where net force
is zero.
minimum energy level.
bonding energy - CORRECT ANSWER - the amount of energy needed to separate two
charged particles at an infinite distance.
ionic bonding properties and reason - CORRECT ANSWER - melting point : strong bonds
brittle : rigid/fixed atom arrangement
electrically insulated : very stable electrons
metallic bonding and ion core - CORRECT ANSWER - ion cores is the nucleus and non-
valence electrons of an atom.
metals are made of this. the valence electrons are shared amongst themselves.
van der Waals forces - CORRECT ANSWER - very weak intermolecular forces of
attraction
IMFs in inert gasses - CORRECT ANSWER - only van der waals
anions for hydrogen bonding - CORRECT ANSWER - fluorine, oxygen, chlorine
metal-ionic bonds - CORRECT ANSWER - bonds of a substance with considerable ionic
and metallic bonds.
