Ernest Rutherford's 1911 model of the atom failed to explain why electrons, which are negatively charged, do not collapse into the positively charged nucleus due to electrostatic forces. This model was unable to account for the stability of the atom.
Ernest Rutherford is credited with the development of the "Rutherford Model" of the atom, which proposed that the atom consisted of a small, dense nucleus containing positively charged protons orbited by negatively charged electrons. This model was developed in 1911 based on experiments conducted in his laboratory.
The planetary model of the atom was proposed by Ernest Rutherford in 1911. This model suggested that electrons orbit the nucleus in a way that is similar to the planets orbiting the sun.
Ernest Rutherford is credited with creating the nuclear model of an atom. In 1911, his gold foil experiment demonstrated that atoms have a small, positively charged nucleus surrounded by a cloud of negatively charged electrons. This model laid the foundation for our modern understanding of atomic structure.

The Rutherford model was the model that showed the discovery of a positively charged nucleus. In this model, proposed by Ernest Rutherford in 1911, he suggested that atoms have a dense, positively charged nucleus at the center, with electrons orbiting around it. This model provided evidence for the nuclear nature of the atom.
This was an idea of Ernest Rutherford (1871-1937) from 1911.

He didn't exactly "discover" the nucleus. In 1911 he theorized about the atom having its positive charges in a very small nucleus. In 1921 he postulated about the existence of the neutron in the nucleus. The first experiment to split the atom in a controlled manner was performed by him and two students in 1932.
John Dalton developed the first modern atomic theory in the early 19th century, proposing that elements are made up of tiny, indivisible particles called atoms. Later, Ernest Rutherford's gold foil experiment in 1911 led to the discovery of the nucleus and the planetary model of the atom.
In 1911, Ernest Rutherford discovered the nucleus of the atom. Rutherford was born in New Zealand in 1871 and became known as the father of nuclear physics.

In 1911 the existence of the atomic nucleus was discovered by Ernest Rutherford through his interpretation of the gold foil experiment conducted two years earlier by Hans Geiger and Ernest Marsden. In 1932 Dmitry Ivanenko proposed the proton-neutron model of the nucleus.
1919 it was actually 1911 http://www.rsc.org/chemsoc/timeline/pages/1911.html
The Geiger-Marsden experiment, which is also called the gold foil experiment or the Rutherford experiment, was conducted by Hans Geiger and Ernest Marsden in 1909, under Earnest Rutherford's direction. You need a link to the Wikipedia post on this ground-breaking experiment, and we've got one for you.
