- Rutherford concluded that the majority of the mass was concentrated in a minute, positively charged region (the nucleus) surrounded by electrons.
- When a (positive) alpha particle approached sufficiently close to the nucleus, it was repelled strongly enough to rebound at high angles.
- The small size of the nucleus explained the small number of alpha particles that were repelled in this way. Rutherford showed, using the method below, that the size of the nucleus was less than about 10−14 m .
- Rutherford atomic model also known as planetary model of the atom, in which nearly all the mass of atom is concentrated at center, around which the light, negative charged particles, called electrons, circulate at some distance, much like planets revolving around the Sun.

Ernest Rutherford Did he become famous straightaway?
Ernest Rutherford discovered that atoms have a very dense nucleus, which contains protons.Rutherford eventually coined the terms for some of the most basic principles in the field: alpha, beta, and gamma rays, the proton, the neutron, half-life, and daughter atomshe found that all known radioactive elements emit two kinds of radiation: positively and negatively charged, or alpha and beta. He showed that every radioactive element decreases in radioactivity over a unique and regular time, or half-life, ultimately becoming stable.He discovered the atomic nucleus and developed a http://wiki.answers.com/dp13at.htmlelof the atom that was similar to the solar system.Rutherford's find came from a very strange experience. Everyone at that time imagined the atom as a "plum pudding." That is, it was roughly the same consistency throughout, with negatively-charged electrons scattered about in it like raisins in a pudding. As part of an experiment with x-rays in 1909, Rutherford was shooting a beam of alpha particles (or alpha rays, emitted by the radioactive element radium) at a sheet of gold foil only 1/3000 of an inch thick, and tracing the particles' paths. Most of the particles went right through the foil, which would be expected if the atoms in the gold were like a plum pudding. But every now and then, a particle bounced back as though it had hit something solid. After tracing many particles and examining the patterns, Rutherford deduced that the atom must have nearly all its mass, and positive charge, in a central nucleus about 10,000 times smaller than the atom itself. All of the negative charge was held in the electrons, which must orbit the dense nucleus like planets around the sun.He was the New Zealand physicist who split the atomFrom: Bradwell Institute Information
What country benefited form Amerigo Vespucci?
United States of America!! A cartographer named the "New World" after Amerigo Vespucci.
Does anyone go to Ernest Gallet Elementary?
YES! ITS THE BEST SCHOOL IN THE WORLD!
What are the two main divisions of science?
According to Ernest Rutherford, physics and stamp collecting, though that's a bit pejorative. One common division is between physical sciences (physics, chemistry, geology, astronomy) and life sciences (biology, medicine, pharmacology).
How did Jane Goodall benefited the world?
Jane Goodall has benefited the world by revolutionizing our understanding of primates through her groundbreaking research on chimpanzees in Tanzania. She has significantly advanced the field of primatology and conservation biology, inspiring generations of scientists and environmentalists to work towards protecting wildlife and preserving habitats. Additionally, her advocacy work has raised awareness about the importance of conservation and the interconnectedness of all living beings on Earth.
What was Ernest Rutherford's goals?
his goals were to save the world
How did ernest Rutherford make a difference in the world you live in?
Ernest Rutherford was a New Zealand-born British physicist who became known as the father of nuclear physics. He discovered the nucleus of the atom in 1911.
What was ernest Rutherford's effects on the world?
Ernest Rutherford's experiments on radioactivity led to the discovery of the atomic nucleus, laying the foundation for our understanding of the structure of atoms. His work ultimately paved the way for the development of nuclear physics and the harnessing of nuclear energy. Rutherford's research also had a significant impact on the field of chemistry, as it helped to establish the concept of isotopes.
Why can you describe ernest Rutherford as a courageous scientist?
He had to persuade the rest of the scientific world that solids were in fact mostly empty space.
What did Ernest Rutherford work on?
Some chemistry experiment involving shooting atoms at gold tin foil..basically finding electrons. However, the question you should be asking in the world of chemistry is: Who is Alice Hoffman?
How has Ernest Rutherford influenced society today?
because he freaked his girl and she freaked and sucked the rest of the world so it got affect
What was Ernest Rutherford religious belief?
Ernest Rutherford, the renowned physicist and father of nuclear physics, was raised in a religious household with strong Presbyterian beliefs. However, as he delved deeper into scientific research, his views shifted towards agnosticism. Rutherford's scientific discoveries and empirical evidence led him to prioritize rationality and skepticism over religious dogma.
Who benefited from the triangular trade?
Africa, The New World, and Europe all benefited from this.
How did ernest Rutherford make the nuclear bomb?
Ernest Rutherford did not make the nuclear bomb. He was a physicist who conducted pioneering work in the field of nuclear physics, particularly on the structure of the atom. The development of the nuclear bomb was primarily led by other scientists during the Manhattan Project in World War II.
Who benefited most from World War 2?
The financiers
Why are scientists concerned about subatomic particles?
For the particles in the atom: Neutron: James Chadwick, 1932 Electron: J. J. Thomson, 1897 Proton: Ernest Rutherford, 1919
