1. 1.

   In a speculative Victorian laboratory, an inventor constructs an analytical apparatus calibrated strictly to the foundational postulates of John Dalton's atomic theory. The apparatus is designed to model chemical transformations by combining hard, indivisible spherical units of distinct elements into compound groupings governed by simple whole-number ratios. When an assistant attempts to reprogram the apparatus to account for atoms splitting into smaller charged fragments and atoms of the same element possessing unequal masses, the apparatus rejects the input. According to Dalton's original atomic model, which explanation correctly justifies this rejection?

   • A) Dalton proposed that atoms consist of uniform spheres of positive charge embedded with smaller corpuscles that cannot vary in mass.
   • B) Dalton posited that atoms are primarily empty space with dense nuclei, meaning their masses can only shift through nuclear reactions.
   • C) Dalton asserted that chemical elements can lose fractional masses during reactions while retaining their energetic identities.
   • D) Dalton maintained that atoms are indivisible, indestructible solid particles and that all atoms of a specific element are identical in mass.
