At the time, there was a model known as the Plum Pudding model theorized by J.J. Thompson. Rutherford wanted to test the validity of this model through the Gold Foil Experiment he performed.
In the plum pudding model, an atom was a mass of positive charge with freefloating electrons inside. Rutherford decided to set up a thin sheet of gold foil upright and through his device, launched alpha particles(positively charged Helium ions) into the gold foil. If an atom truly did have a mass of positive charge with freefloating electrons inside, the the alpha particles should have all just gone straight through the foil to the other side, with minor bending in direction.
However, while most did do so, many of the alpha particles bounced into several different, wide and dramatic angles-some even bounced straight back. This led to the theory that there must be a concentrated source of positive charge within the atom causing such rebellious deflection upon contact with the alpha particles, rather than the entire atom being a mass of positive charge.
its was Ernest Rutherford who proposed the planetary atomic model
Probably you refer to Ernest Rutherford.
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.
why was Ernest Rutherford's nickname lord Rutherford
The early theory of atomic structure that described electrons as moving around a central nucleus similar to the solar system is known as the Rutherford atomic model. Proposed by Ernest Rutherford in 1911, this model suggested that electrons orbit the nucleus in defined paths.
Rutherfordium was not discovered by Ernest Rutherford.
Ernest Rutherford is not known for studies in magnetism.
Rutherfordium was named after Rutherford
Ernest Rutherford worked in Manchester (UK) and at Mac Gill (Canada).
Because he wanted to.
in 1897
Ernest Rutherford was responsible for the Gold Foil experiment. A great portion of Ernest Rutherford's research included the study of alpha particles.
The proton was discovered by Ernest Rutherford in 1917. Rutherford identified the proton while conducting experiments on the structure of the atom.
Ernest Rutherford created the nuclear model of an atom!
Gold foil experiment.
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.
