Question

1. match the statements with the pictures. answers can be used more than once. atomic model proposed by dalton atomic model proposed by rutherford atomic model proposed by bohr atomic model based off of discoveries by heisenberg and schrödinger atomic model proposed by j. j. thomson model shows negative electrons floating in a “soup” of positively charged material model shows that the atom is not further divided into subatomic particles model shows that electrons can only travel in discrete orbits at specific distances from the nucleus model shows a positively charged core that is surrounded by mostly empty space and negatively charged electrons orbiting the core

Explanation:

• Dalton's atomic model (the atom is not further divided into sub - atomic particles) is a solid sphere, corresponding to A.
• Rutherford's model has a positively charged core (nucleus) surrounded by mostly empty space and negatively charged electrons orbiting the core, corresponding to E.
• Bohr's model shows electrons can only travel in discrete orbits at specific distances from the nucleus, corresponding to D.
• The model based on discoveries by Heisenberg and Schrödinger is the quantum mechanical model which has electron clouds, corresponding to B.
• J. J. Thomson's model shows negative electrons floating in a "soup" of positively charged material (plum - pudding model), corresponding to C. Also, the description "model shows negative electrons floating in a 'soup' of positively charged material" matches C, and "model shows that the atom is not further divided into subatomic particles" matches A.
