An ionic compound is formed from positive and negative ions which have balanced and opposite charges.K has 1 electron in it's outer shell. S has 6 electrons in it's outer shell. S needs 2 more electrons t...
In the atomic structure of diamond, each carbon is bonded to four other carbons using all of its outer electrons, leaving none free to carry a charge. In graphite not all of the electrons are used in bond...
Increase the surface area of the magnesium, for example by using a powder.Increase the temperature of the reaction.Add a catalyst
(a) Ionic bonding. Ions are free to move/flow(b) So only one product is produced at each electrode OR So that the cathode/anode stays negative/positive which allows only the positive/negative ions to reac...
