1. Complete the following sentence by selecting the appropriate
choices from the drop down boxes.

The periodic trend for ionization energy states that typically
ionization energy increases to the right across a period. This is
because as effective nuclear charge increases to the right across a
period, the valence electrons experience a stronger attraction to
the nucleus and therefore require more energy to be
removed.
2. For this question, PREDICT the order using the
TRENDS for each periodic property



(a) Based on your knowledge of the periodic trend
in first electron affinity, place the
following in order
of INCREASING electron
affinity such that 1 is the element with
the lowestpredicted first electron affinity and 5 is
the element with the highest predicted first
electron affinity.


1 2 3 4 5 Sn
1 2 3 4 5 S
1 2 3 4 5 W
1 2 3 4 5 Os
1 2 3 4 5 Te
(b) Based on your knowledge of the periodic trend
in first ionization energy, place the
following in order
of INCREASING first
ionization energy such that 1 is the element with
the lowest predicted first ionization energy and
5 is the element with the highest predicted
first ionization energy.


1 2 3 4 5 Cs
1 2 3 4 5 Mn
1 2 3 4 5 Zn
1 2 3 4 5 Zr
1 2 3 4 5 Sr
(c) Based on your knowledge of the periodic trend
in atomic radius, place the following in
order
of INCREASING atomic
radius such that 1 is the element with
the smallest predicted atomic radius and 5 is
the element with the largest predicted atomic
radius.


1 2 3 4 5 Ta
1 2 3 4 5 Zn
1 2 3 4 5 Cl
1 2 3 4 5 Mo
1 2 3 4 5 Ru
3. Complete the following sentence by selecting the appropriate
choices from the drop down boxes.

A beryllium cation with a +1 charge
(Zeff = 1 2 3 4 5 6 7 8 )
is smaller larger than a beryllium atom
(Zeff = 1 2 3 4 5 6 7 8 )
due to having more less protons
than electrons causing
a(n) increased decreased attraction to the
nucleus. Similarly, a beryllium anion with a -1 charge
(Zeff = 1 2 3 4 5 6 7 8 is smaller larger than
a beryllium atom due to
having more less protons than
electrons causing
a(n) increased decreased attraction to the
nucleus.
