Atomic Orbitals – Class Warmup
Determine whether each of the following
statements is true or false. If it is false,
explain what is wrong with the statement.
•
•
An s orbital is always spherical in shape.
Answer: True
The 2s orbital is the same size as the 3s
orbital.
Answer: False. The 2s orbital is smaller
than the 3s.
Atomic Orbitals
• The number of lobes on a p orbital increases as
“n” increases. That is, a 3p orbital has more
lobes than a 2 p orbital.
Answer: False. The shape of the p orbital does
not change from energy level to energy level.
Only the size changes.
• Principle energy level 1 has one s orbital, level 2
has two s orbitals, level 3 has three s orbitals,
and so on.
Answer: False. In each energy level, there is only
one s orbital
Atomic Orbitals
• The electron path is indicated by the surface of
the orbital.
Answer: False. An orbital is a region of
space where it is likely to find and
electron. Electrons do not follow a defined
path and orbitals do not have surfaces.
• The shape of a given type of orbital changes as
“n” increases.
Answer: False. The shape does not
change. The size DOES change.
Atomic Orbitals
• The number of sublevels in a given energy
level is the same as the value of “n”.
Answer: True
• The hydrogen atom has a 3s orbital.
Answer: True. In the ground state,
the orbital is empty.
