"Prediction is very difficult‚ especially about the future". The words are by Niels Bohr‚ the father of the atom as we know it. A Man of Many Interests I. Niels Bohr‚ ironically known as ’the Pope’ among his colleagues‚ was born in 1885‚ in Copenhagen‚ where he lived for most of his life. He created the Institute for Theoretical Physics‚ now known as the Niels Bohr Institute‚ where he mentored and collaborated with the best scientists of his time. II. Bohr’s interests ranged

This led to the calculation of possible energy levels for these orbits and the postulation that the emission of light occurs when an electron moves into a lower

Niels Bohr is a big person in the history of chemistry. If it wasn’t for him we would not have known as much as we do now about the atom. He came to a conclusion of so many unanswered questions people were left after the discovery of the electron. He also participated in the United State’s biggest project that helped us win World War II. If it wasn’t for Niels Bohr we probably would not have as many things as we do today. He is one‚ if not‚ the biggest person in the history of Chemistry. Niels

Atomic Theorist Niels Bohr Niels Bohr was born on October 7‚ 1885 in Copenhagen‚ Denmark. His father was Christian Bohr‚ a prominent physiologist and a professor at Copenhagen University. His mother was Ellen Adler Bohr‚ the daughter of a wealthy Jewish banker. As Bohr grew up‚ he was surrounded with his fathers work. This ignited his interest in physics from a young age. Bohr enrolled in Copenhagen University in 1903 to study physics. He received his masters in 1909 and then a doctors degree in

He made large contributions to the field of quantum mechanics and also in the understanding of atomic structure. Niels Bohr worked on the well known Manhattan Project‚ and received the Nobel Prize for Physics in 1922. Niels Bohr

Models of the Atom a) Plum Pudding Model The plum pudding model imagines the atom as a positively charged entity that contains randomly dispersed (negative) electrons within it. It is called the plum pudding model because the electrons in the positively charge cloud resemble raisins in a pudding. Thomson realized that all atoms must contain electrons‚ and since the atoms had a neutral charge‚ they must also include protons. This led him and other to think of the atom as a positively charged

He shows how Moseley proved that the element’s atomic number is more important than the element’s atomic weight. This proved to be important because back then

BOHR’S MODEL OF ATOM MADE BY:-GROUP-1{CHEMISTRY} About The Scientist……. HE 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. Bohr was also a philosopher and a promoter of scientific research. He was born in Copenhagen on 7 October 1885. He wrote many books like the theory of spectra and atomic constitution‚ atomic theory and the description of nature. NEILS BOHR (1885-1962)

The Balmer series is characterized by the electron transitioning from n ¡Ý 3 to n = 2‚ where n refers to the radial quantum number or principal quantum number of the electron. The transitions are named sequentially by Greek letter: n = 3 to n = 2 is called H-¦Á‚ 4 to 2 is H-¦Â‚ 5 to 2 is H-¦Ã‚ and 6 to 2 is H-¦Ä. As the spectral lines associated with this series are located in the visible part of the electromagnetic spectrum‚ these lines are historically referred to as H-alpha‚ H-beta‚ H-gamma and
