Question

8 le modèle de dalton compare les atomes aux blocs d’un jeu de construction. en quoi les atomes et les blocs de construction se ressemblent-ils ?

9 le mot «atome» vient du mot grec atomos qui signifie: «que l’on ne peut diviser ou couper». cette

Explanation:

For Question 8:

Dalton's atomic model views atoms as the basic building blocks of matter, similar to construction blocks (like Lego) which are basic units. Atoms combine to form compounds (molecules) just as construction blocks combine to make larger structures. Both are indivisible in the context of their role as fundamental units for building (atoms for matter, blocks for structures), and they combine in specific ways (atoms in fixed ratios for compounds, blocks in various ways for constructions). Also, a specific type of atom is identical (same mass, properties) like a specific type of construction block is identical.

Answer:

Atoms and construction blocks are both fundamental, indivisible (in their role of building) units that combine to form larger entities: atoms combine to form molecules/compounds, and construction blocks combine to form larger structures. Atoms of a given element are identical (same mass, properties), like identical construction blocks, and they combine in specific ways (atoms in fixed ratios for compounds, blocks in designed ways for constructions).
