easy · MCAT chem-phys
A chemist compares the properties of Nitrogen (Z = 7) and Phosphorus (Z = 15). Phosphorus is expected to have a lower electronegativity than Nitrogen because:
- Phosphorus is a metal while Nitrogen is a non-metal.
- Phosphorus has a higher atomic number, which always decreases pull.
- Its valence electrons are more shielded and further from the nucleus.
- Nitrogen has a higher ionization energy, which is unrelated to electronegativity.
