They usually react with ions of opposite charge to form neutral compounds. For example, positive sodium ions and negative chloride ions react to form the neutral compound sodium chloride, commonly known as table salt. This occurs because oppositely charged ions attract each other. Ions with the same charge, on the other hand, repel …
DetailsFor the ionic compound between Mg 2 + ions and Cl − ions, we now consider the fact that the charges have different magnitudes: 2+ on the magnesium ion and 1− on the chloride ion. To balance the charges with the lowest number of ions possible, we need to have two chloride ions to balance the charge on the one magnesium ion.

DetailsA: . Stability of carbocations Carbocation is an electron deficient species. So, electron withdrawing groups further increases the deficiency of electrons and destabilises the carbocation.
DetailsIons with opposite charges attract each other, and ions of the same charge repel each other. Because they are charged, ions which travel through a magnetic field are deflected by it. Ions can occur in gases and liquids, but tend to rapidly join with ions of the opposite charge and neutralize each other. Metal Ions. Metal ions in a sea of electrons.

DetailsA monatomic ion's charge depends on its place in the periodic table. Atoms that lose electrons become positively charged ions, or cations. Atoms that gain electrons become negatively charged ions, or anions. Polyatomic Ions Polyatomic ions contain more than one atom and behave as a unit.
DetailsNote the usefulness of the periodic table in predicting likely ion formation and charge (Figure (PageIndex{2})). Moving from the far left to the right on the periodic table, main-group elements tend to form cations with a charge equal to the group number. That is, group 1 elements form 1+ ions; group 2 elements form 2+ ions, and so on.
