What equipment was use to discover the nucleus is dense and the atom is mainly empty space?
This is usually referred to as the 'gold foil' experiment.
1. You need some radiation source that releases alpha particles. This is placed inside a lead box (to block radiation) with a small pin hole to allow the escaping alpha particles to move in one direction.
2. A piece of gold foil, very thin, to be a target for the radiation.
3. A scintillation screen. (phosphorescent screen, that emit a light when struck by the alpha particles)
4. A really dark room to carry out the experiment.
5. Some kind of magnifying device to enable you to see the very weak light when an alpha particle hits the screen.
6. Some way to measure the angles of deflection of all the particles from the screen to the screen.
What else can I help you with?
What is the dense center portion in a nucleus in a cell?
The nucleus.
What did Rutherford discover about the volume of the nucleus?
Rutherford discovered that the nucleus occupies a very small volume compared to the overall size of the atom. He found that the nucleus is extremely dense and contains nearly all the mass of the atom, while the rest of the atom is mostly empty space.
Which is more dense the nucleus or the electron cloud?
The nucleus is significantly more dense than the electron cloud. The nucleus contains most of the mass of an atom, while the electron cloud occupies a much larger volume with a very low density.
The part of the atom that is small and dense is?
The nucleus is the small and dense center of an atom. It contains protons and neutrons, which are the subatomic particles that make up the majority of the atom's mass.
What are small agranulocytes that have a dense nucleus and very little cytoplasm?
Small agranulocytes that have a dense nucleus and very little cytoplasm are called Lymphocytes.
How did Rutherford discover that there was a dense solid nucleus of an atom?
He picked up a piece of metal and looked at it REALLY carefully, and he could see inside the atoms.
What is the dense center portion in a nucleus in a cell?
The nucleus.
What is the most dense part of an atom?
The nucleus is the most dense part of an atom.
What is the dense center of the atom called?
the denser part of an atom is the nucleus. about 99% of the mass of an atom is concentrated within the atom.
What is a dense in area in a cell that contains nucleic acids?
The dense area in a eukaryotic cell that contains nucleic acid is the nucleus.
Why is the nucleus of the atom so dense?
the nucleus has a very dense centre because it has to be large enough to contain numerous amounts of particles.
What subatomic particle did the gold foil experiment discover?
Rutherford's gold foil experiment did not discover the existence of any subatomic particles, but it did show the existence of a small, tightly packed, positively charged nucleus and thus led to the discovery of protons.
Rutherford concluded from his calculations that the volume of an atom is?
Mainly empty space, with a very small and dense nucleus at the center containing the majority of the atom's mass.
What did Rutherford discover about the volume of the nucleus?
Rutherford discovered that the nucleus occupies a very small volume compared to the overall size of the atom. He found that the nucleus is extremely dense and contains nearly all the mass of the atom, while the rest of the atom is mostly empty space.
Rutherford pictures the atom as a dense what?
nucleus
What is a true statement about a nucleus?
They are very dense
Dense area of nucleus?
Within the nucleus are one or more dense regions called nucleoli. Their function is to synthesize ribosomal RNA and assemble ribosomes.
