Examine the following model of an
atom.
How can you determine if this element
is reactive or inert?
a. | Round the atomic mass to the nearest whole number. Then
subtract the atomic number. | b. | Count the total
number of electrons. If this amount is greater than 20, then the element is
inert. | c. | Count the number of electrons in the outer shell.
If the shell is full, the element is non-reactive. | d. | Add the number of protons and neutrons. If the sum is more than 10, the
element is inert. |
