How does a cation differ from an anion? Why do ions conduct electricity? How do polyatomic ions behave in an ionic compound? Why do ionic compounds conduct electricity? Explain why cations tend to form ions with radii smaller than their neutral atom. Why are ionic compounds electrically neutral?
When an ionic compound is formed, the cation and anion attract each other, resulting in a salt. An important thing to remember is that the compound must be neutral — that is, it has equal numbers of positive and negative charges. Putting magnesium and bromine together Suppose...
how exactly does electrolysis occur if the molar conductivities of cation and anion are different? ask question asked 3 years, 6 months ago modified 3 years, 5 months ago viewed 188 times 6 i'm having trouble wrapping my head around kohlrausch law of infinite dilution...
By definition, atoms are neutral entities because the positive charge of the nucleus is cancelled by the negative charge of the electron cloud. However, the gain or loss of an electron can lead to the formation of an ion, also known as a charged atom.
The easiest way to determine whether a compound can conduct a current is to identify its molecular structure or composition. Compounds with strong conductivity dissociate completely into charged atoms or molecules, or ions, when dissolved in water. These ions can move and carry a current effectively...
use the trick of cross-transferring oxidation states between the ions to determine the count of each cation and anion involved. this trick works because the formula should denote an electrically neutral species. (you can verify this mathematically) so, to write the formula f...
Write the symbols for the cation and anion that make up the ionic compound Ag2O. Determine the formula and check if the given compound is ionic or covalent, acid or hydrate. Cupric oxide What is the formula for the ionic compound formed by calcium and selenium?
A carbon triple-bound to a nitrogen by itself rather than attached to a carbon chain is simply a cyanide anion. For example KCN = Potassium Cyanide dissociates into a K+ cation and the CN- anion. The nitrile or cyano group will show up mostly in advanced orgo 2 reactions. ...

in an atom equals the number of electrons, the atom remains uncharged, or neutral. When an atom gains or loses electrons, it becomes an electrically charged ion. An atom that gains electrons becomes a negatively charged anion. An atom that loses electrons becomes a positively charged cation....
