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 else can I help you with?
What technology helped Ernest Rutherford discover the atom?
Ernest Rutherford used the technology of radioactivity and conducted the famous gold foil experiment to discover the structure of the atom. By directing alpha particles at a thin gold foil, he observed how they were deflected, which led to the understanding that atoms have a small, positively charged nucleus at their center.
Who invented Rutherford's nuclear 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.
What did Ernest Rutherford discover about the structure of an atom?
Ernest Rutherford discovered that atoms have a small, positively charged nucleus at the center, surrounded by electrons in empty space. This nucleus contains most of the atom's mass and is where the protons are located. This model is known as the nuclear model of the atom.
Who said most of an atoms mass is in the nucleus in an atom?
Ernest Futher Ford
Who discovered that atoms have a dense center and called it the nucleus?
Ernest Rutherford is credited with discovering that atoms have a dense center called the nucleus in his famous gold foil experiment in 1911. He found that most of the mass and positive charge of an atom is concentrated in the nucleus, with electrons orbiting around it.
Why did ernest Rutherford discover the atom?
Because he wanted to.
When did Ernest Rutherford discover the nucleus of the atom?
in 1897
Where did Ernest Rutherford discover the structure of the atom?
Ernest Rutherford worked in Manchester (UK) and at Mac Gill (Canada).
Who discover proton by 1886?
The proton was discovered by Ernest Rutherford in 1917. Rutherford identified the proton while conducting experiments on the structure of the atom.

When did Ernest Rutherford discover rutherfordium?
Rutherfordium was not discovered by Ernest Rutherford.
When did Bohr discover that most of an atom's mass is in the nucleus?
Bohr did not discover this. Ernest Rutherford 'discovered' the nucleus. This was done in 1911.
What is the name of first scientist to ever split the atom?
Ernest Rutherford was the man you are thinking of. He was the first person to 'split the atom'.
