∙ 13y ago- 2 of his brothers drowned in 1886
- He was denied permission to teach each time he applied for a job
- He was born with and umbilical hernia which killed him when it was left untreated for too long.
Hope this helps.

∙ 12y agoA short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.
Also Rutherford discovered atomic nucleus and the proton.

What are the major models on the structure of the atom?
There are many, but here are the main ones: 1) Dalton's Billiard Ball Model 2) Thompson's Plum Pudding Model 3) Lewis's Cubical Atom Model 4) Rutherford's Planetary Model 5) Bohr's Model 6) Schrodinger's Electron Cloud Model
How did ernest Rutherford discover the atom?
Ernest Rutherford develop the idea that the atom has nucleus by using gold foil and alpha particles. Basically He shot the poistive laser to the gold foil which contains positive and negitive, and he saw the reflection of it and it tells us that there is positive charge to reflect positive laser with is proton. J.J Thomson already discover the electron, who has negative charge. Then Rutherford figured out the nucleus is positive.
What are the main points of Rutherford's nuclear model of an atom?
1.Positive charged particle is present at the center of an atom and it is known as the nucleus which consists of the major mass of the atom. 2.The atoms are neutral due to the presence of equal charge of negatively charged electron and positive charged nucleus. 3.The electrons move around the nucleus as the planets move round the sun and the centrifugal force of nucleus is equal to the charge of the moving electrons.
Problems with Rutherford model?
In Rutherford's model of the atom the electrons had a circular motion around the nucleus. By the laws of physics, if something is going in a circular motion then it must be accelerating and a particle that accelerates is losing energy. This means that the electrons that are revolving around the nucleus would eventually fall into the nucleus. Nucleus would eventually collapse. This does not happen therefore the Rutherford model was put aside.
How many negative charges are in the atom?
That depends on what element it's an atom of. In a neutral atom of Hydrogen . . . 1 In a neutral atom of Uranium . . . 92 In a neutral atom of any other naturally occuring element . . . between 2 and 91.
Who discover subatomic particle?
There are 3 subatomic particles in an atom, electrons, protons, and neutrons. The first discovered was the electrons by J.J. Thomson in 1897. The second discovered was the protons by Ernest Rutherford in 1919. The third discovered was the neutrons by James Chadwick in 1932.
What did Rutherford's gold-foil experiment help him conclude?
When Rutherford put the gold foil in front of the alpha-particle emitting source, he noticed a few things: 1. Some of the alpha particles passed through the gold foil 2. Some the particles were deflected 3. Some of the particles bounced back Rutherford concluded that an atom is made up of mostly empty space and the actual size of the atom is far smaller than the space it occupies.
What is the structure of the atom as proposed by Rutherford?
Before Rutherford, scientists assumed that the atom was a single particle. Rutherford presented his revolutionary, physical atomic model that suggested an atom consists of a central charge (the term 'nucleus' was coined after Rutherford's model was presented) that is surrounded, presumably, by a cloud of orbiting electrons. He showed that most of an atom's mass was located in the atom's nucleus. Rutherford's model was later improved upon by Niels Bohr, father of the Bohr-model. Rutherford made no connection to an element's atomic number and the number of protons within an atom's nucleus; however, his atomic model paved the way for the discovery of this correlation only a couple years after his model was designed.
What did Rutherford infer as a result of his observations?
Rutherford Discovered Many key factors of the atom. Especially about Protons and Electrons. He Did Not Know about neutrons. He Concluded That The atoms electron cloud was positive and electron floated around it like chocolate chips in a cookie.
Do Rutherford's gold foil experiment led to the discovery of the portion of the atom known as the nucleus?
shail = whale to the power of 2
What is the nuclear models of the atoms?
It is called the "nuclear model" Rutherford concluded that 1. Atom is mostly empty space 2. Atom has a nucleus at its center 3. Electrons surround the nucleus
What are the three subatomic particles and their symbols?
1. Proton: a particle from the atomic nucleus, positive charge, mass approx. 1 u.a.; discovered by Ernest Rutherford in 1919. 2. Neutron: a particle from the atomic nucleus, neutral, mass approx. 1 u.a.; discovered by James Chadwick in 1932. 3. Electron: a particle from the atom, negative charge, very low mass; discovered by J. J. Thomson in 1932.
Who discovered particles?
Actually there are many subatomic particles from them following were discovered by: 1)Electron discovered by J.J Thomson through discharge tube experiment. 2)Proton was discovered by Ernest Rutherford through discharge tube experiment. 3)Neutron was discovered by James Chadwick by Artificial radioactivity.
An atom releses an bata particle. what two things does an atom lose. the element becomes?
It loses 2 proton and 2 nutron
What is the Bohr-Rutherford diagram of the fluorine atom?
9 protons and 10 neutrons, two rings with 2 protons in the first ring and 7 protons in the second.
Who discovered that an atom is mostly empty space?
Rutherford's Experiment In this expt, Alpha particles (Double positive charged helium atom) were bombarded on a thin gold foil. Observation:- 1) Most of the rays passed straight through it without any deflection...(Answer to ur question) 2) Some rays were deflected through an small angle giving the sense of presence of Electrones 3) 1 out of 20000 rays was was deflected right back through the same path ( Nucleus )
What are 2 things that Isaac Newton discovered?
He discovered gravity, the three laws of motion, and the color spectrum.
