Question

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

Answer 1

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.

Answer 2

The calcium atom has the weakest attraction for electrons in a chemical bond
