Asubstance that has atoms of 2 or moreDIFFERENT ELEMENTS chemically bonded together (Ex: NaCl)BOND = forces of ATTRACTION between the protons (nucleus) of one atom and the electronsof another atom. Only VALENCE electrons participate in bonding. Bonds are formed as a resultof a CHEMICAL REACTION. We are talking about bonding BETWEEN ATOMS(Intramolecular) (Within the molecule) (Holds the molecule together).Sharing or transferringofelectronsforms the chemical bond.1
A chemical bond is represented by-------- which means a pair of electrons. -------=O O =2e-Example.H2,H-H orHHHow many pairs of electrons?______#e=Cl2,Cl –Cl, orClCl.How many pairs of electrons?_____#e=O2,O = O, orOO.How many pairs of electrons?______#e=N2,NNorNN.
What happens after a chemical bond is formed?
