It can be deduced that some atoms tend to form ions to acquire the number of electrons of the noble gases because the electron arrangements with these numbers of electrons are very stable.

  • Ti → atomic # = 22

Problem Details

While it is helpful to know that many ions have the same number of electrons as a noble gas, many elements, especially among the metals, form ions that do not have the same number of electrons as a noble gas.

Use the periodic table shown below, to determine which of the following ions have the same number of electrons as a noble gas.

The periodic table consists of elements arranged in order of increasing atomic number. Periods are horizontal rows in the table while groups are vertical columns containing elements with similar properties. The elements are divided into metals, which make up the center and left part of the table (except for hydrogen), nonmetals, which make up the far right of the table, and the six metalloids between the metals and nonmetals. A steplike line in the table divides the metals from nonmetals, running between the metalloids (B, Si, Ge, As, Sb, and Te).

Check all that apply.


a) Zn 2+ 

b) Te2−

c) Ti4+

d) Mn2+ 

e) Pb2+
