Niels Bohr was interested in understanding what was going on inside an atom.
Electrons should move around the nucleus but only in prescribed orbits. He took Balmer's formula and was able to explain it through usage of the quantum theory, now giving it a reason for why wavelengths of hydrogen could be found. You will receive a verification email shortly.There was a problem. Bohr's Atomic Model Following the discoveries of hydrogen emission spectra and the photoelectric effect, the Danish physicist Niels Bohr (1885 - 1962) proposed a new model of the atom in 1915. About a hundred years ago, a young Danish scientist named Niels Bohr wondered the same thing.

These types of atoms rarely exist on their own but are almost always bonded to others in order to maintain a full outer electron shell. Just a year later, he married Margrethe Norlund and they went on to have a total of 6 children, including one son, Aage, who would eventually win a Nobel Prize in physics, just like his father! Niels Henrik David Bohr was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922. He was good in all subjects relating to school, but was weak when it came to speaking Danish, which is ironically his maiden tongue. - Biography, Atomic Theory & Discovery 8:41 In school he was attracted to physics, fixing errors he found in textbooks. credit-by-exam regardless of age or education level.Not sure what college you want to attend yet? In 1920, he was appointed the head of the Institute for Theoretical Physics.Combining Rutherford's description of the nucleus and Planck's theory about quanta, Bohr explained what happens inside an atom and developed a picture of atomic structure. In science, a scientific modelis an idea about how nature works that can be tested and used to explain many observed phenomena. © The study of the emission and absorption spectra of atoms was crucial to the development of a successful theory…

He asserted that the electron in a hydrogen atom occupies one of an array of discrete (but infinite… He spent many years studying the atomic nucleus and how it could be fissioned to release energy. Right: A stylized representation of a lithium atom illustrates Niels Bohr's atomic model, that an atom is a small, positively charged nucleus surrounded by orbiting electrons.

The Bohr model shows the atom as a small, positively charged nucleus surrounded by orbiting electrons. It was important to him, however, to use his skills for good and not violence. The orbits are labeled by an integer, the quantum number This article was most recently revised and updated by 7:29 If atoms don't already have eight atoms in their outer electron shell, they tend to bond with other atoms to complete the outer shell and be more stable. "Every great and deep difficulty bears in itself its own solution. and career path that can help you find the school that's right for you.Get the unbiased info you need to find the right school.© copyright 2003-2020 Study.com. The Bohr model of the atom, a radical departure from earlier, classical descriptions, was the first that incorporated quantum theory and was the predecessor of wholly quantum-mechanical models.

His curiosity and research would lead him to develop a new model of the atom, known today as the Bohr model.

Betsy teaches college physics, biology, and engineering and has a Ph.D. in Biomedical EngineeringYou probably know that all matter is made up of really, really tiny particles called atoms, but have you ever wondered exactly how an atom works and what the inside of one looks like?
