The proof that most of an atom's mass is concentrated at its center comes from experiments such as Rutherford's gold foil experiment. When alpha particles were fired at a thin gold foil, most passed through, but some were deflected at large angles, indicating a dense, positively charged nucleus at the center. This led to the conclusion that the nucleus contains the majority of the atom's mass, while the electrons orbit around it, constituting a small part of the overall mass. Subsequent developments in nuclear physics further confirmed this model.
What else can I help you with?
Where in a atom are protons found?
Protons are found in the nucleus of atoms along with the neutrons of the atom. The nucleus is always in the centre of the atom.
What makes up the centre of an atom in chemistry?
The center of the atom is the nucleus formed from protons and neutrons.
What is the basic structure of an atom as postulated by Bohr?
the centre has a nucleus
What are the locations of proton electron and neutron?
In an atom- the protons and neutrons are in the nucleus(centre) which makes the middle positively charged. The electrons are around the nucleus. The electrons are attracted to the nucleus because the nucleus is positively charged.
What is about 10-5NM and found at the center of an atom?
nucleus is found at the centre of an atom. however the size of the nucleus is about 10-12 nm
How was it proved that whole mass of an atom is located at its centre?
,Rutherford alpha scattering experiment proved that most of the particles passed through the gold foil undeflected it means most of the volume occupied by atom is empty and few particles deflected it means there is centre of positive charged called nucleus,so hence proved whole mass of an atom is located in the centre..
Where is the proton located in the atom?
In the centre.
Where is protons and neutrons located?
in the nucleus, the centre of the atom
Where in a atom are protons found?
Protons are found in the nucleus of atoms along with the neutrons of the atom. The nucleus is always in the centre of the atom.
Where are proton neutron and electron located inside an atom?
Protons and neutrons are present in the nucleus. Electrons are present in orbits of an atom. Where as proton are located at centre of the nucleus.
Where is most of the mass located in an atom and why?
in the centre within nucleus where protons and neutrons are located.protons and neutrons have atomic mass of 1 u each while electrons revolving around have mass=0u[almost negligible]. so most of the mass is located in centre of an atom.
Centre of an atom is composed of positive nucleus?
Yes, the centre of a chemical atom is a positive nucleus.
What is the centre of an atom?
nucleus
What is the discovery of which particle proved that the atom is not indivisible?
protons
Where in the atom are neutrons?
Neutrons can be found in the centre of the atom (the nucleus), along with protons.
What is the name for the centre of the atom containing the protons and neutrons?
That would be the nucleus of the atom
How was it proved that the whole mass of an atom is located at its center?
The discovery of the nucleus by Ernest Rutherford in the early 20th century provided evidence that the majority of an atom's mass is concentrated in a small, dense region at the center. Rutherford's gold foil experiment demonstrated that most of the alpha particles passed through the foil undeflected, indicating the presence of a concentrated mass at the center of the atom. This led to the development of the nuclear model of the atom, which suggests that the nucleus contains the majority of an atom's mass.
