How has the atomic model changed over time?

The model of the atom has dramatically changed over many many years. We learned atoms make up different substances and are the smallest particles of matter, which have subatomic particles that are very small portions of matter. At first scientist only thought there were electrons which are negatively charged.Click to see full answer. People also ask, how has the atomic theory changed over time?In chemistry and physics, the atomic theory explains how our understanding of the atom has changed over time. Atoms were once thought to be the smallest pieces of matter. However, it is now known that atoms are made up of protons, neutrons, and electrons.Likewise, why do models change over time? Models are testable ideas describing natural phenomena. The model of a flat Earth was based on observations from land. These are examples of models changing over time as technology and equipment improve and ideas become modified. Models seek to represent objects, phenomena and physical processes in a logical way. Besides, how was the atomic model developed? In 1913, Neils Bohr, a student of Rutherford ‘s, developed a new model of the atom. He proposed that electrons are arranged in concentric circular orbits around the nucleus. This model is patterned on the solar system and is known as the planetary model. Electrons occupy only certain orbits around the nucleus.What is the current atomic model?1 Answer. Paul N. Generally speaking, the Bohr model encapsulates the modern understanding of the atom. This model is often depicted in artwork showing a central atomic nucleus and oval lines representing the orbits of the electrons.
