Question

1. choose the best answer.

what is the central atom in this lewis structure?
nitrogen
hydrogen

Explanation:

In a Lewis structure, the central atom is typically the one with the lowest electronegativity (among non - hydrogen atoms) and can form the most bonds. Here, nitrogen (\(N\)) is more electronegative than hydrogen (\(H\)), but hydrogen can only form one bond. Nitrogen can form three bonds (as seen in \(NH_3\), which this Lewis structure represents). The structure shows one \(N\) atom bonded to three \(H\) atoms, so \(N\) is the central atom.

Answer:

nitrogen
