The nuclear model of an atom
WebApr 7, 2024 · Niels Bohr proposed a model of the atom in which the electron was able to occupy only certain orbits around the nucleus. This atomic model was the first to use quantum theory, in that the electrons were limited to specific orbits around the nucleus. Bohr used his model to explain the spectral lines of hydrogen. WebThis 3D atom model activity is an engaging way to teach atomic structure. Students will learn how to collect element data and use the information to design a 3D atom model. Each 3D model consists of four Bohr models glued together. Students can complete the models independently, or you can save paper by allowing students to work in groups of four.

In 1898, J. J. Thomson proposed the first of many atomic models to come. He proposed that an atom is shaped like a sphere with a radius of approximately 10-10 m, where the positive charge is uniformly distributed. The electrons are embedded in this sphere so as to give the most stable electrostatic arrangement.
WebDalton proposed that every single atom of an element, such as gold, is the same as every other atom of that element. He also noted that the atoms of one element differ from the atoms of all other elements. Today, we still know this to be mostly true. A sodium atom is different from a carbon atom.
