Question

How do you determine if an element or compund is electron rich? please provide examples.

Answer 1

Answer - We know the electron rich means the element or compound with high density on element or compound. We know the electronegativity of the element means the tendency of element pulling the electron density towards itself. When the element is more electronegativity means it pull the electron density toward self and formed partial negative charge. The element or compound with partial negative charge is electron rich.

We know the covalent compound has also polarized means the compound with bond have more difference in the electronegativity then there is formed two pole that is the partial negative and partial positive and the negative side has more electron density and it is gets electron rich.

Examples – HCl, HF, H₂O

In the HC the electronegativity for H is 2.2 and Cl has 3.16, so Cl has more electronegativity than H and it has more electron density than H in the HCl compound. So in the HCl Cl element is electron rich than H.
