Week 25: Elements Have different Charges.

Week 25


W hile in the process of discovering what's behind the mystery of electyricity, we uncovered that particles at least have negative, electrons within them and a surplus and or a diffiency of electrons causes an repulsion or an attraction between the two substances. As  both substances need the other to stay neutral  they form a strong bond called an Ionic Bond. Above is an example of How NaCl, or salt is formed. Sodium has an extra electron having a surplus of  electrons and a negative charge. Chloride hasv a diffiency of electrons and has positive charge. Together, the one negative sodium atom and the one positive chloride atom cancel the chrges out becoming a neutral  sodium chloride molecule.

Sometimes it takes more than one  of each atom, as the charges vary. the charges are +1 +2 +3 +/- 4
-3 -2 -1in that order wit ha last column that is neutral. With  each ionic bond there is at least one Cation (+) and an Anion (-) the Cation always goes first when writing out the Formula name. The Anion always changes its name so endss  with "ide", this is how we know  the name of  of salt is called Sodium Chloride and not Cloride Sodide or anything like that.  So without the use of  any real positive  particles, we can explain ionic bond soley with a surplus and or a diffiency of electrns.
