Question

explain atomic structure and who found it.(detail)

Answer 1

atom is the smallest unit of matter.atoms center is called nucleus which consist of neutron and proton and electrons revolve around nucleus in orbit s .proton has positive charge neutron is neutral and electrons carry negative charge.the atom was discovered by John Dalton

Answer 2

Neal Bohr found the atomic structure of atom. he states that in the center of atom their are proton and neutron and electrons are revolve around it.
the are three postulate of Bohr
postulate 1:;;;;
in hydrogen atom, an electron revolves in circular orbit round the nucleus .The centripetal force for the circular motion is provided by the electrostatic force of attraction between the positively charge nucleus and negatively charge electron.

postulate2
the electron can revolve withaut radiating energy in those orbits in which angular momentum of the electron is equal to an integral multiple of h/2pie. ,where h is the planks constant.



third postulate is....................
An electron radiates energy when it jumps from outer stationary orbit of higher energy to lower energy.this radiated energy is equal to difference between the energies of electron in two orbit. this energy is radiated in the form of photon of energy.
