i got this charterer from this website but the copy from google
a long long ago in a science lab. A scientist named Niels Bohr discovered ATOMS
Niels Bohr was bornCopenhagen, Denmark
Niels bohr modle shows the atoms as a small, positive charged nucleus surrounded by orbiting electrons. niels bohr was the first to discover that electrons travel in separate orbit around the nucleus and that the number of the electrons in the outer orbit determines the properties of an element.
FACTS ABOUT NIELS BOHR 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. Bohr was also a philosopher and a promoter of scientific research.
niels bohr use a drawing model to show his actions and the way.
nucleus containing protones and neutrones
electrons move around the necluse
WHAT WAS THE EXPERIMENT OF NIELS IN 1913, Niels Bohr proposed a theory for the hydrogen atom based on quantum theory that energy is transferred only in certain well defined quantities. Electrons should move around the nucleus but only in prescribed orbits. When jumping from one orbit to another with lower energy, a light quantum is emitted.
