Electrоnegаtivities аre shоwn in the chаrt tо the right. Only the first and next-to-last element in each row is labeled, but the rest are indicated by dots. If you compare the electronegativites for elements in column 5A to elements in column 7A in the same row of the periodic table, what do you find? (For example, if you compare nitrogen to fluorine or compare phosphorus to chlorine.) Image Description Graph of electronegativity based on atomic number. Hydrogen, with an atomic number of 1, is shown with an electronegativity of 2.2. Lithium, with an atomic number of 3, is shown around 1, with a path of dots increasing toward Flourine, which has an atomic number of 9, at around 4 electronegativity. Sodium, with an atomic number of 11, is shown around 0.9, and has a path of dots increasing toward Chlorine, which has an atomic number of 17, at around 3.2 electronegativity. Potassium, which has an atomic number of 19, is shown around 0.8, and has a path of dots leading toward Bromine, which has an atomic number of 35, at around 2.9 electronegativity. What can you conclude about the molecule?
