What Compounds Undergo Ionic And Covalent Bonding?

What determines whether a bond is covalent or ionic is determined ny the difference in electronegetivity of the to bonding atoms. If the two atoms are fairly similar like carbon-barbon bonds the electrons within that bond are shared equally between the two atoms. Atoms that have a greater difference as in carbon halide compounds(MethylBromide)CH3Br, you have Carbon atom and a more electronegetive atom like bromine to cause the bond to be polarized toward the Bromide atom(this is where most of the electron density will be found, this bond is a polar covalent bond, which is a weaker bond, and more reactive than a straight covalent bond. The compound tha have atoms with the greatest electronegetivity difference will for ionic compounds. Salts like KCl are formed when K loses its electron to form an octet around sodium as well giving it a + charge, the Cl is so electronegative that it wants the electron given up by the Na atom and then carries a -(neg.) charge. The attraction between the two ions form a salt that has the strongest bond or interaction of the three.
