Atomic Structure

Because group 13 was the first to cross the metal-nonmetal split, its chemistry is more diverse than that of groups 1 and 2, which include just metals. The group 13 elements, with the exception of boron, are all electropositive, meaning they lose electrons rather than gain them in chemical reactions. The 13th element group is

In chemistry and atomic physics, the electron shell can be thought of as an orbital of electrons around the nucleus. The shell closest  to the nucleus is called the “1 shell” (also called the “K shell”), then the “2 shell” (or “L shell”), then the “3 shell” (or “M-shell”), etc., further away from the nucleus.

Introduction to hydrogen spectrum A hydrogen atom consists of two protons and two electrons held together by electrostatic forces. This force leads to a set of quantum states, each with its own energy. These states were envisioned by the Bohr model of the hydrogen atom as being different orbits around the nucleus.Each energy level, electron

Bohr’s atomic model explains that the negatively charged electrons orbit around the positively charged protons in the nucleus. The energy levels determine how the electrons move. Bohr assumed that the electrons travel in orbits at a certain radius. It was later proved wrong by Werner Heisenberg in his uncertainty principle. Bohr’s model also does not

An atom contains electrons, neutrons, and protons. The structure of atoms has been formulated by many scientists. But the most favourable and well-explained model was given by scientist Ernest Rutherford. This model is recognized as Rutherford’s atomic model. So, let us discuss in detail Rutherford’s atomic model and their limitations, his theories, and experiments. Body

During the race in finding out the right model that could represent the atomic structure, many scientists came and the second amongst them was a physicist from New-Zealand named Ernest Rutherford. Rutherford again did his studies with respect to the Thomson model and for that he couldn’t agree much, so he decided to do his

Ernest Rutherford (and his students Hans Geiger and Ernest Marsden) performed an experiment popularly known as the alpha ray scattering experiment to study atoms. Before him, a scientist named Thomson had experimented to study atoms and their characteristics known as Thomson’s model. He reached many conclusions regarding the structure and position of electrons, neutrons, and

According to Danish physicist Niel Bohr’s atomic model, an atom includes a small, charged nucleus surrounded by electrons that journeys in round orbits across the nucleus with force supplied through electrostatic forces. This version of Bohr’s theory was entirely based on Planck’s quantum principle of radiation. Bohr’s atomic principle became massively popular in explaining the
