Which atom has the weakest attraction for electrons in a chemical bond? (1) a boron atom (3) a fluorine atom(2) a calcium atom (4) a nitrogen atom

The (2) calcium atom, because when looking at the periodic table, we see that the calcium atom is in a location where according to the periodic table, has the lower electronegativities in respect to the other three choices. We see that it also has a lower electronegativity value than the others. Electronegativity is the attraction constant for the electrons in a chemical bond. The higher the electronegativity, the higher the attraction of the electrons. Fluorine has the highest electronegativity with 4.0.

Copper, silver, aluminum, cobalt, chromium, mercury
