





63x + 65y = 63.546
63(1-y) + 65y = 63.546
63 – 63y + 65y = 63.546
2y = .546
Y = .273
So … 63Cu is 72.7% abundant and
65Cu
is 27.3% abundant

Question Fifty Eight
•How many electrons
would an ion of
tellurium have?
54
Question Fifty Nine
• Which has a higher
ionization energy,
sodium or chlorine, why?
Chlorine because it is in the same
energy level as chlorine, but has
more protons … so harder to remove
an electron from it
Question Sixty
• Which has a larger
atomic radius, lithium or
rubidium? Why?
Rubidium because more energy levels
means electrons are found farther
from nucleus – and therefore atom is
bigger
Question Sixty One
• Which will have a higher
melting point, chromium
or neon? Why?
Chromium because chromium is a solid
at room temperature and neon is a
gas at room temperature (chromium
is a metal and neon is a nonmetal)
Question Sixty Two
•Which will have a
greater density, gold
or xenon? Why?
Gold b/c gold is a metal (solid)
and xenon is nonmetal (gas)
Question Sixty Three
• Which will have a higher
electron affinity, calcium
or arsenic? Why?
Arsenic because it is in the same
energy level and it has more protons
– so it will release more energy when
an electron is added
Question Sixty Four
• Which will have a higher
ionization energy,
oxygen or selenium?
why?
Oxygen because electrons are closer
to nucleus due to less energy levels –
so harder to remove the electron
from the valence shell.
Question Sixty Five
• Which will have a larger
atomic radius, carbon or
fluorine? Why?
 Carbon will have a larger atomic
radius because it is in the same
energy level but has less protons – so
less of a pull on the valence shell.
Question Sixty Five and a Half
•Write the shorthand
electron configuration
for lead
[Xe]6s24f145d106p2
Question Sixty Six
• Which will have a higher
electron affinity, nitrogen
or antimony? Why?
Nitrogen because the electrons are
closer to the nucleus since there are
fewer energy levels – so the nucleus
would be better able to hold onto an
additional electron.
