ACS CHEMISTRY GENERAL EXAM 2024 ACTUAL EXAM VERSION A
COMPLETE 200 QUESTIONS WITH DETAILED VERIFIED ANSWERS
ALREADY GRADED A+
Forms of the same elements that differ in amount of
neutrons - CORRECT ANSWER >>>>isotopes
When alpha particles were shot at a metal foil target,
most passed through without deflections, while others
deflected at large angles. What did this suggest to
Rutherford? - CORRECT ANSWER >>>>that the atoms of
the metal were mostly empty space, while the nucleus
consisted of most of the mass which included highly
condensed positive particles (which caused the
deflection).
electromagnetic spectrum - CORRECT ANSWER
>>>>Greater wavelength = lower frequency
greater frequency = shorter wavelength
,2|Page
Electrons configuration rule that states electrons do not
pair until they have to. (put one electrons in each
electron domain then pair up) - CORRECT ANSWER
>>>>Hund's rule
An experimental phenomena associated with atoms
having unpaired electrons - which states such substances
are attracted to magnetic fields - CORRECT ANSWER
>>>>Paramagnetism
What do the 4 quantum numbers stand for? - CORRECT
ANSWER >>>>n = energy level
l = (n-1)
ml -l to l
mn 1/2 or -1/2 (spin)
List the quantum numbers for the s, p, d, and f orbitals -
CORRECT ANSWER >>>>s 1,0,0
p 2, 1, -1-0-1
d 3, 2, -2--1-0-1-2
f 4, 3 -3--2--1-0-1-2-3

What two subatomic particles have the most mass, but
occupy very little of the volume of an atom - CORRECT
ANSWER >>>>protons and neutrons
Define Isoelectronic - CORRECT ANSWER >>>>Having the
same amount of electrons
How does a sodium ion differ from a sodium atom? -
CORRECT ANSWER >>>>the sodium ion has fewer
electrons
two or more compounds with the same formula but a
different arrangement of atoms in the molecule and
different properties - CORRECT ANSWER >>>>isomer
two or more different physical forms in which an
element can exist. Graphite, charcoal, and diamond are
all ________ of carbon. - CORRECT ANSWER
>>>>allotropes
What did Millikan discover from his oil drop
experiments? - CORRECT ANSWER >>>>the magnitude of
the charge on an electron
