strengths: -electrons move fast through the atom. -electrons are trapped within the atom by a positively charged nucleus -electrons are negatively charged. weaknesses: -failed to discover the nucleus contains positively charged particles called protons -failed to discover the nucleus also contains neutrons (a sub atomic neutral particle)
Dalton's model of an atom, proposed in the early 19th century, viewed the atom as a solid, indivisible sphere. He believed that atoms of different elements had different masses and sizes, and that they combined in simple whole number ratios to form compounds. However, this model was later replaced by more advanced atomic models that better explained the behavior of atoms.
The nickname for Thompson's atomic model is the "plum pudding model." This model suggests that atoms are made up of a positively charged "pudding" with negatively charged electrons embedded within it, resembling plums in a pudding.
Dalton's atomic model was often referred to as the "Billiard Ball Model" because he envisioned atoms as solid, indivisible spheres similar to billiard balls.
The atomic model has been refined from "the plum pudding" model,to a nucleus with orbiting electrons,to an awareness of many different sub atomic particles in the nucleus and electrons that are in energy levels,to electrons in sub energy levels and in distinct orbitals with different associated energy and behaviour
The atomic model was developed by various scientists over time, with contributions from Niels Bohr, Ernest Rutherford, and John Dalton. However, the modern atomic model that we use today, with electrons existing in energy levels around a nucleus, was largely proposed by Niels Bohr in 1913.
The idea that atoms are indivisible.

thomas discovered that the atom contained smaller particals called electrons
Dalton's theory was irrelevant to the total compensation of of the Atomic Mass.
Dalton's atomic theory or model was accepted despite errors. This is because his theory provided a logical explanation of concepts and led the way to new experimentations.
Strengths of the multi-store model include its simplicity and ability to explain how information is processed in the brain in a linear manner. Weaknesses include oversimplification of memory processes and lack of consideration for the dynamic and interactive nature of memory systems.
Thomson's experiments with cathode ray tubes helped him to discover the electron (which Dalton did not know about). Dalton thought that atoms were in.

Strengths of the medical model of abuse include its focus on individual pathology and treatment, which can lead to effective interventions. Weaknesses include its failure to address societal factors contributing to abuse and the potential for victim blaming by pathologizing abusers.
Strengths of the seafloor spreading model include providing a mechanism for the movement of tectonic plates, explaining the age and magnetic patterns of the ocean floor, and supporting the theory of plate tectonics. Weaknesses include the lack of direct observation of seafloor spreading, the complexity of the processes involved, and the challenge of accurately dating oceanic crust.
