What are examples of electronigativity?

Answer 1

In water H binds with 2O H has the smaller nucleus and therefore has less ability to attract the electrons in the covalent bond and therefor the H becomes slightly positive [denoted as delta+] and the O becomes slightly negative [denoted as delta-].

There will be electronegativity where any two elements with different sized nucleuses and different shielding form a covalent bond. Other example would be ammonia (NH3) and ammonium (NH4).

Answer 2

Examples of electronegative elements include fluorine, oxygen, and nitrogen. These elements have a strong affinity for electrons and tend to attract them towards themselves when forming chemical bonds.
