(16 cards)
Which of the following elements has the smallest atomic radius?
A. Na +
B. S2-
C. Mg2+
D. N3-
E. Al 3+
first convert all to the actual element, if you have one that is the same look for the one with the highest + charge
in this case
E. Al 3+
Which of the following elements is most electronegative?

Si
Cl
B
Cl
Which of the followings has the largest 1st Ionization energy?
Na
K
Mg
Li
Cs
Mg
Which of the following Ions has the largest 2nd ionization energy?
Na+
Mg+
Ca+
Al+
Ba+
Na+

When comparing Lithium to Carbon, Carbon has ______.
smaller atomic radius and higher ionization energy
higher electronegativity and larger atomic radius
lower electronegativity and lower ionization energy
higher electronegativity and lower ionization energy
larger atomic radius and lower ionization energy
smaller atomic radius and higher ionization energy
Which of the followings has the smallest atomic radius?
Fluorine
Chlorine
Bromine
Iodine
All have the same radius
Fluorine
Which of the following elements would have the lowest electronegativity?
Li
Na
K
Rb
Cs
Cs
Which of the following pairs of elements has the greatest difference in electronegativity?
Li and F
Na and Cl
Be and O
K and Br
