Bonding Between Cations and Anions

Postby Tiffany_Cacy_3D » Fri Oct 26, 2018 2:27 pm

When you have an example like the one that professor went over during lecture with 2 cations and 1 anion where do they bond together if they all have full valence shells? I believe the example was ammonium sulfate (NH4)2+ (SO4)2-

In the case of (NH4)+ and (SO4)2-, (NH4)+ only has a full valence shell because it gave up one of its electrons, generating a positive charge and (SO4)2- only has a full valence shell because it stole two electrons, generating the negative 2 charge. Cations and anions form ionic bonds through this transfer of electrons. Covalent bonds are the bonds that share electrons to form full valence shells.

When he drew the Lewis structure of the entire molecule, he drew the SO4 molecule between the NH4 molecules, without including any of the lines that indicate bonding.

(NH4)2+ and (SO4)2- are cations and anions which form an ionic bond through the transferring of electrons.
