Learning ObjectivesState the octet rule. Define ionic bond. Draw Lewis constructions for ionic compounds.
In Section 4.7, we demonstrated that ions are formed via losing electrons to make cations, or by gaining electrons to form anions. The astute reader may have spotted one thing: lots of the ions that form have eight electrons in their valence shell. Either atoms acquire enough electrons to have eight electrons in the valence shell and turn out to be the correctly charged anion, or they lose the electrons in their unique valence shell; the lower shell, now the valence shell, has 8 electrons in it, so the atom becomes positively charged. For no matter explanation why, having 8 electrons in a valence shell is a in particular energetically strong arrangement of electrons. The octet rule explains the favorable development of atoms having eight electrons of their valence shell. When atoms form compounds, the octet rule is not at all times glad for all atoms at all times, but this can be a superb rule of thumb for figuring out the kinds of bonding arrangements that atoms could make.
It isn't unattainable to violate the octet rule. Consider sodium: in its elemental shape, it has one valence electron and is solid. It is quite reactive, on the other hand, and does no longer require a large number of energy to take away that electron to make the Na+ ion. We may take away some other electron through including much more energy to the ion, to make the Na2+ ion. However, that calls for much more power than is usually available in chemical reactions, so sodium stops at a 1+ rate after dropping a unmarried electron. It turns out that the Na+ ion has a complete octet in its new valence shell, the n = 2 shell, which satisfies the octet rule. The octet rule is a result of developments in energies and comes in handy in explaining why atoms shape the ions that they do.
Now believe an Na atom in the presence of a Cl atom. The two atoms have these Lewis electron dot diagrams and electron configurations:
\[\mathbfNa\, \cdot \; \; \; \; \; \; \; \; \; \; \mathbf\cdot \mathbf\ddot\underset.\: .Cl\mathbf\: :\]
\[\left [ Ne \proper ]3s^1\; \; \; \; \left [ Ne \proper ]3s^23p^5\]
For the Na atom to procure an octet, it should lose an electron; for the Cl atom to realize an octet, it must gain an electron. An electron transfers from the Na atom to the Cl atom:
\[\mathbfNa\, \cdot \curvearrowright \mathbf\cdot \mathbf\ddot\underset.\: .Cl\mathbf\: :\]
resulting in two ions—the Na+ ion and the Cl− ion:
\[\mathbfNa^+\; \; \; \; \; \; \; \; \mathbf:\mathbf\ddot\underset.\: .Cl\mathbf\: :^-\]
\[\left [ Ne \right ]\; \; \; \; \; \left [ Ne \proper ]3s^23p^6\]
Both species now have whole octets, and the electron shells are energetically solid. From elementary physics, we all know that reverse charges attract. This is what happens to the Na+ and Cl− ions:
\[\mathbfNa^+\; + \; \mathbf:\mathbf\ddot\underset.\: .Cl\mathbf\: :^-\rightarrow Na^+Cl^-\; \; or\; \; NaCl\]
where we have written the overall system (the components for sodium chloride) as according to the conference for ionic compounds, without list the costs explicitly. The attraction between oppositely charged ions is known as an ionic bond, and it is among the major forms of chemical bonds in chemistry. Ionic bonds are led to via electrons transferring from one atom to any other.
In electron switch, the number of electrons lost will have to equivalent the collection of electrons won. We noticed this in the formation of NaCl. A an identical procedure occurs between Mg atoms and O atoms, apart from in this case two electrons are transferred:
The two ions each and every have octets as their valence shell, and the 2 oppositely charged particles attract, making an ionic bond:
\[\mathbfMg\,^2+\; + \; \left[\mathbf:\mathbf\ddot\underset.\: .O\mathbf\: :\right]^2-\; \; \; \; \; Mg^2+O^2-\; or\; MgO\]
Remember, in the final method for the ionic compound, we don't write the fees at the ions.
What about when an Na atom interacts with an O atom? The O atom wishes two electrons to finish its valence octet, however the Na atom supplies just one electron:
\[\mathbfNa\, \cdot \curvearrowright \mathbf\cdot \mathbf\ddot\underset.O\mathbf\: :\]
The O atom still does now not have an octet of electrons. What we'd like is a 2d Na atom to donate a 2d electron to the O atom:
These 3 ions attract each other to provide an overall neutral-charged ionic compound, which we write as Na2O. The want for the choice of electrons misplaced being equal to the selection of electrons gained explains why ionic compounds have the ratio of cations to anions that they do. This is needed by the law of conservation of topic as smartly.
Example \(\Web pageIndex1\): Synthesis of Calcium Chloride from Elements
With arrows, illustrate the transfer of electrons to form calcium chloride from \(Ca\) atoms and \(Cl\) atoms.
A \(Ca\) atom has two valence electrons, while a \(Cl\) atom has seven electrons. A \(Cl\) atom needs just one more to finish its octet, while \(Ca\) atoms have two electrons to lose. Thus we'd like two \(Cl\) atoms to just accept the 2 electrons from one \(Ca\) atom. The switch procedure appears as follows:
The oppositely charged ions draw in every different to make CaCl2.
With arrows, illustrate the transfer of electrons to form potassium sulfide from \(Ok\) atoms and \(S\) atoms.Answer
