Additionally, I rely on research-based evidence, referencing previous studies and theoretical models to support my claims and provide a comprehensive and objective analysis of H2O’s lattice energy.

Electronegativity and Lattice Energy

The electronegativity of elements directly affects the lattice energy of a compound. In the case of H2O, the lattice energy is influenced by several factors that can be analyzed from a technical perspective:

  1. Bond lengths: The distance between the oxygen and hydrogen atoms in the water molecule affects the strength of the electrostatic forces between ions in the lattice. Shorter bond lengths lead to stronger attractions and higher lattice energy.
