It was Ernest Rutherford who discovered that atoms are mostly composed of empty space with electrons orbiting a very dense nucleus.

What did Rutherford proposed?
He proposed a new model of the atom in which there is a small dense positively charged nucleus with negatively charged electrons around the outside. The electrons are far away in comparison to the size of nucleus, so the majority of the atom is made up of empty space.
How did Thomson help our understanding of the atom?
He discovered that the atom contained smaller particles called electrons.
What are found in the space surrounding the nucleus of an atom?
The space around the nucleus of an atom is called the electron cloud. The electron cloud is the space in which the electrons of that atom travel. Compared to the nucleus, the electron cloud is enormous.
Do atoms have empty space?
Yes. In 1908, Rutherford conducted an experiment of shooting a beam of alpha particles through a sheet of tinfoil. Most of the alpha particles went straight through the foil, which proves that there are empty spaces in atoms. And the rest of the particles that didn't go straight through the foil are deflected at acute angles, those particles are deflected by the positive nucleus in the center of the atoms.
What was Rutherfords main contribution to science?
He discovered that most of the mass of an atom and all of thepositivecharge are in the centre. Most of the atom is 'empty' space, occupied by electrons, which orbit thenucleus.Gold Foil ExperimentHe shot streams of alpha particles (Helium nuclei) through a thin gold foil and discovered most of them passed through and a minority deflected back. As alpha particles are positively charge, that means the nucleus of atoms are also positive as it deflects alphas away. (pos-pos,repeland neg-pos, attract)
What was significance of rutherfords experiment?
He discovered that the atom was mostly made up of empty space.
Who discovered the plum pudding model of atom?
J.J. Thompson created the "Plum Pudding" model of the atom. He was inaccurate, though, in stating that the electrons are embedded in a positively charged particle cloud. Ernest Rutherford, then, using alpha particles, surmised that an atom is mostly empty space, and that the empty space contains electrons.
What was the significance of Rutherford's experiment?
Rutherford's experiment, known as the gold foil experiment, led to the discovery of the atomic nucleus and the development of the nuclear model of the atom. This experiment provided evidence that most of the atom's mass and positive charge is concentrated in a small, dense nucleus at the center of the atom, with electrons orbiting around it. It revolutionized our understanding of atomic structure.
Discovered the nucleus and that atom was composed of mostly empty space?
Rutherford
Who first came up with the idea that the atom is mostly empty space?
The idea that the atom is mostly empty space was first proposed by Ernest Rutherford based on his gold foil experiment in 1909. This experiment led to the discovery that most of an atom's mass is concentrated in a nucleus at the center, surrounded by electrons in vast empty space.
Is almost all the volume of an atom empty space?
Yes, the majority of an atom's volume is indeed empty space. At the center of the atom is a dense nucleus containing protons and neutrons, while electrons orbit around the nucleus in distinct energy levels. The space between the nucleus and the electrons is where most of the atom's volume is found.
True or false Most of an atom is empty space?
True. The protons and neutrons together are dense and comprise most of the mass of the atom. The electrons "circle" around in a "cloud" so there is empty space in between the electrons.
If an atom is mostly empty space what keeps other matter from moving through the space inside an atom?
The empty space within an atom is not truly "empty" but is occupied by the nucleus and electrons. These particles interact through electromagnetic forces that repel other matter from moving through the space inside an atom. The forces between the particles maintain the structure and integrity of the atom.
How do you prove that volume of an atom is chiefly empty space?
The mass and volumes of electrons are not significant compared to the volume of an atom.
What was the significance the Rutherford's experiment?
He discovered that the atom was mostly made up of empty space.
Who saw the atom as mostly empty space with electrons orbiting around the nucleus?
Rutherford.
What is mostly between electrons?
In an atom, the space between electrons and the nucleus is mostly filled with empty space. The nucleus contains positively charged protons and neutral neutrons, and the electrons surround the nucleus in different energy levels or electron shells.
