Arrange the following atoms or ions in order of decreasing
ionization energy:
K+, Cl-, S2-,
Ca2+
Please show how you get the answer. I am confused because
all of the ions would be like the nearest noble gas. So wouldn't
all of them have the same ioniation energy?

Consider the following binds Ca-O, C-O, K-O, O-O and N-O
a Which bonds are polar covalent ?
b Wich bonds are nonpolar Covalent
c Which bonds are ionic ?
d Arrange the covalent bonds in order of decreasing polarity
1. the first ionization energy of Ca is greater than the first
ionization energy of K, but the second ionization of Canis lower
than the second ionization energy of K. Explain.
2. Compare the hybridization of the sulfur atom in the molecules
SF_2, SF_4, and SF_6
3. Assign formal charges to each atom in NH_4^+, SO_3^-2, and
XeF_2
which are true:
A) The 2nd ionization energy for k would be represented using
the equation K+(g) --> K2+(g)+e-
B) the first ionization energy of Br should be smaller than the
first ionization energy of Br2-
C) the successive ionization (in a hypothetical unit) for an
unknown element are IE1=200, IE2=300, IE3=425, IE4=2500. The
possible identity of the element is Be.
