How does model of helium help in current atomic theory?
Compare the positions of the electrons in bohr's model of the atom with their positions according to modern atomic theory?
He contriubuted to modern science with his model for atomic theory which he described was similar to the rings of saturn and he descibed that in his model of atomic theory. Hantaro Nagaoka was a great man and and he contributed alot of tings to modern science i cant name them all but he contributed alot of things to modern science
No. A law is a description of an observed pattern in the universe. A theory is a model that explains observations. E.g. atomic theory explains many of the things that matter does. There will not be a time in the future when we will call it "atomic law" because the model of atoms is concerned with explaining the behavior of matter, not describing it.

The most commonly seen atomic theory is an amalgamation of the Rutherford and Bohr models, and therefore referred to a the Rutherford-Bohr model(1913) The most modern one is a model formed from theories by Werner Heisenberg and Ernest Schrodinger as well as others and is referred to as the Atomic orbital model(1927), but has been greatly improved on since then
The proportions at which elements occur in the observable universe closely match predictions of the Big Bang theory. According to this model, only the simplest elements would have condensed from the primordial quark-gluon plasma: hydrogen and helium. Heaver elements would have formed inside the first stars and supernovae. Most of the visible matter in the universe would therefore be hydrogen and helium, with heavier elements in lesser numbers, proportional to their atomic weight.
