Final answer:
Nitrogen has a higher electronegativity than boron due to having more protons, more valence electrons, and its position in the periodic table.
Step-by-step explanation:
The question addresses the concept of electronegativity, which is a chemical property. Nitrogen has a higher electronegativity than boron primarily due to its higher number of protons and closer proximity to the top right of the periodic table, which typically indicates higher electronegativities. Since nitrogen has five valence electrons, it is closer to completing its octet, compared to boron's three valence electrons, and hence, nitrogen more strongly attracts electrons to itself. Additionally, the strong triple bond in molecular nitrogen (N₂), which demonstrates the need for nitrogen atoms to complete their outer shells, contributes to the understanding of nitrogen's high electronegativity. In summary, elements with greater numbers of valence electrons and those closer to filling their outer electron shell will have higher electronegativity values.
