Which element is less electronegative?

Electronegativity is an important concept in chemistry that refers to the ability of an atom to attract shared electrons in a chemical bond. In a covalent bond, electrons are shared between atoms, and the electronegativity of each atom determines how strongly it attracts the shared electrons.

In the case of niobium (Nb) and strontium (Sr), the electronegativity values play a crucial role in determining which element is less electronegative. Niobium has an electronegativity value of 1.6, indicating that it has a relatively high tendency to attract shared electrons. On the other hand, strontium has an electronegativity value of 0.95, which is lower than that of niobium.

Therefore, based on the electronegativity values of niobium and strontium, we can conclude that strontium (Sr) is less electronegative than niobium (Nb). This means that in a covalent bond, strontium is less likely to attract shared electrons towards itself compared to niobium.
