What family of the periodic table would element X be most likely to belong (refer to the ionization energy values for element X from the table below)? What charge would you expect element X to have when it forms an ion?

First ionization energy 900 kJ/mol
Second ionization energy 1750 kJ/mol
Third ionization energy 14900 kJ/mol
Fourth ionization energy 21000 kJ/mol

Below are data on the first four ionization energies for a fictitious element X.

First ionization energy = 500 kJ/mol

Second ionization energy = 1000 kJ/mol

Third ionization energy = 3500 kJ/mol

Fourth ionization energy = 4000 kJ/mol

From the data, which of the following statements is CORRECT?

Select one:

a.
The third ionization energy is smaller than the second ionization energy because    The third ionization energy is smaller than the second ionization energy because   
X 3+    has a bigger charge than    X 2+ . X3+   has a bigger charge than    X2+.

b.
X could belong to Group IIA. X could belong to Group IIA.

c.
X could belong to Group IIIB. X could belong to Group IIIB.

d.
X could belong to group VA. X could belong to group VA.

e.
The fourth ionization energy is much smaller than the third ionization energy because    
X 3+    consists of a noble-gas core or a pseudo-noble-gas core. X3+   consists of a noble-gas core or a pseudo-noble-gas core.

Periodic Properties I

A hypothetical element, X, has the following ionization energy values:

First ionization energy: 900 kJ/mol

Second ionization energy: 1750 kJ/mol

Third ionization energy: 14,900 kJ/mol

Another element, Y, has the following ionization energy values:

First ionization energy: 1200 kJ/mol

Second ionization energy: 2500 kJ/mol

Third ionization energy: 19,900 kJ/mol

Fourth ionization energy: 26,000 kJ/mol  

  1. To what family of the periodic table would element X be most likely to belong? Explain?
  2. What charge would you expect dement X to have when it forms an ion?  
  3. If you were to place elements X and Y into the periodic table, would element Y be in the same period as element X? If not in the same period, where might they be relative to each other in the periodic table?
