What is the opposite of electronegativity, which measures an element's ability to donate electrons?
What is the opposite of electronegativity, which measures an element's ability to donate electrons?
- Electron affinity
- Ionization energy
- Valence electron attraction
- Electropositivity (correct)
Why is oxygen more electronegative than nitrogen?
Why is oxygen more electronegative than nitrogen?
- Oxygen has 8 protons in the nucleus whereas nitrogen only has 7.
- Oxygen has 2 energy levels, while nitrogen has 3.
- The bonding electrons in nitrogen are further away from the nucleus of the atom.
- A bonding pair of electrons will experience more attraction from the oxygen’s nucleus than from nitrogen’s. (correct)
