WebMar 25, 2024 · The solid sphere model proposed by John Dalton stated that atoms consisted of negative charges embedded in a solid continuum of positive charge. The magnitude of the embedded negative charge would cancel the positive charge of the continuum, rendering the entire atom neutral. WebThis is the lattice formed by carbon atoms in a diamond (Conway and Sloane 1993, p. 113). Random close packing of spheres in three dimensions gives packing densities in the range 0.06 to 0.65 (Jaeger and Nagel 1992, Torquato et al. 2000).
