Answer:
The ocean currents are too strong by the Amazon River to form deltas.
Explanation:
The Atlantic has sufficient wave and tidal energy to carry most of the Amazon's sediments out to sea, thus the Amazon does not form a true delta. The great deltas of the world are all in relatively protected bodies of water, while the Amazon empties directly into the turbulent Atlantic.
 
        
             
        
        
        
The three factors determine the chemical properties of an element: 
<span><span>The number and arrangement of electrons in an atom 
</span><span>The number of valence electrons 
</span><span>The number and arrangement of electrons</span></span>
        
                    
             
        
        
        
Iodine has an electronegativity of 2.5, and potassium has an electronegativity of 0.8, so the difference is:
2.5 - 0.8 = 1.7
