Question

Who said that nucleus contains positive protons as well as negative electrons?

Answer 1

Electrons exist in orbital layers outside of the nucleus, which contains the proton(s) and in most cases, neutron(s).

IDK who said otherwise, but they're obviously mistaken.

Answer 2

ur wrong. the nucleus contains only positively charged protons.

the electrons revolve around the nucleus.

Answer 3

E.Rutherford in his nuclear theory.

          But in1920 in his bakerian lecture to the Royel Society, Rutherford proposed that under some conditions..........it may be possible for an electron to combine with proton , forming a kind of neutral doublet. This neutral doublet was further identified as NEUTRON by James Chadwick in 1932.

Answer 4

You seem to be describing J. J. Thomson's "plum pudding" model.  Thomson theorized that the atom was a big positively charged ball with a bunch of little negatively charged electrons inside of it (hence the "plum pudding" reference).
