Question

please tell me about structure of atom

Answer 1

 The basic structure of an atom includes a tiny, relatively massive nucleus, containing at least one proton and usually one or more neutrons

Answer 2

the modern atomic model of atom states that the atom has a central dense positive core
with proton and neutron bound by nuclear force and the electrons r found orbiting in some regions around the nucleus where they are more likely to be found called as orbitals
There r other particles like quarks and pentaquarks that make up the subatomic particles
