Question

Identify the atoms that correspond to each of the following electron configurations. Then, write the Lewis symbol for the common ion formed from each atom: (a) \({\text{1}}{{\text{s}}^{\text{2}}}{\text{2}}{{\text{s}}^{\text{2}}}{\text{2}}{{\text{p}}^{\text{5}}}\) (b) \({\text{1}}{{\text{s}}^{\text{2}}}{\text{2}}{{\text{s}}^{\text{2}}}{\text{2}}{{\text{p}}^{\text{6}}}{\text{3}}{{\text{s}}^{\text{2}}}\) (c) \({\text{1}}{{\text{s}}^{\text{2}}}{\text{2}}{{\text{s}}^{\text{2}}}{\text{2}}{{\text{p}}^{\text{6}}}{\text{3}}{{\text{s}}^{\text{2}}}{\text{3}}{{\text{p}}^{\text{6}}}{\text{4}}{{\text{s}}^{\text{2}}}{\text{3}}{{\text{d}}^{{\text{10}}}}\) (d) \({\text{1}}{{\text{s}}^{\text{2}}}{\text{2}}{{\text{s}}^{\text{2}}}{\text{2}}{{\text{p}}^{\text{6}}}{\text{3}}{{\text{s}}^{\text{2}}}{\text{3}}{{\text{p}}^{\text{6}}}{\text{4}}{{\text{s}}^{\text{2}}}{\text{3}}{{\text{d}}^{{\text{10}}}}{\text{4}}{{\text{p}}^{\text{4}}}\) (e) \({\text{1}}{{\text{s}}^{\text{2}}}{\text{2}}{{\text{s}}^{\text{2}}}{\text{2}}{{\text{p}}^{\text{6}}}{\text{3}}{{\text{s}}^{\text{2}}}{\text{3}}{{\text{p}}^{\text{6}}}{\text{4}}{{\text{s}}^{\text{2}}}{\text{3}}{{\text{d}}^{{\text{10}}}}{\text{4}}{{\text{p}}^{\text{1}}}\) .

Step-by-Step Solution

Answer

The Lewis symbol for each atom is:

Step 1: Define Chemical Bonding

A chemical bond is an interaction between atoms/molecules that allows chemical compounds to form.

Step 2: Writing the Lewis symbol

The letter \({\text{F}}\) stands for atom.

\({{\text{F}}^{\text{ - }}}\) is a common ion.

The following is the Lewis symbol:-

Step 3: Writing the Lewis symbol

The letter \({\text{Mg}}\) stands for atom.

\({\text{M}}{{\text{g}}^{{\text{2 + }}}}\) is a common ion.

The following is the Lewis symbol:-

Step 4: Writing the Lewis symbol

The letter \({\text{Zn}}\) stands for atom.

\({{\text{F}}^{{\text{2 + }}}}\) is a common ion.

The following is the Lewis symbol:-

Step 5: Writing the Lewis symbol

The letter \({\text{Se}}\) stands for atom.

\({\text{S}}{{\text{e}}^{{\text{2 - }}}}\) is a common ion.

The following is the Lewis symbol:-

Step 6: Writing the Lewis symbol

The letter \({\text{Ga}}\) stands for atom.

\({\text{G}}{{\text{a}}^{{\text{3 + }}}}\) is a common ion.

The following is the Lewis symbol:-
