17
Why does
ionization energy decrease
as you move
down a group
on the periodic table?

23
Silicon electrons can be found in the
third energy level
.
False

24
The
most electronegative
elements are found in the
upper right
hand corner.
True
False
25
Why does the
size of atomic radii decrease
as you move
left to right
?
More protons (which pulls in electrons toward the center)
Less electrons (because they tend to lose electrons)
More neutrons (which make the atom more compact)
More electrons (which increase the size of the atom)
