Ernest Rutherford's experiments on the scattering of alpha particles by a thin sheet of gold foil led to the discovery of the atomic nucleus and the realization that atoms contain a central, positively charged nucleus called the proton.

Who are the discovery of atom?
The discovery of the atom is attributed to the work of multiple scientists throughout history, such as John Dalton, J.J. Thomson, Ernest Rutherford, and Niels Bohr. These scientists made significant contributions through their experiments and theories that led to our current understanding of the atom as the basic building block of matter.
How was the discovery of the protons initiated the development of the periodic table of elements?
The discovery of protons helped scientists understand the atomic structure of elements. By knowing that each element has a specific number of protons in its nucleus, scientists were able to organize the elements based on their atomic number, which led to the development of the periodic table. This organization revealed patterns in the properties of elements and facilitated the prediction of properties of undiscovered elements.
Use discovery in a sentence?
Scientists made an exciting discovery when they found a new species of plant in the rainforest.
What tool did scientists use to gather observations to form the cell theory?
Scientists used microscopes to gather observations that led to the formation of the cell theory. These observations allowed scientists to see and study cells, leading to the discovery of their structure and function.
The work of which scientists was largly ignored during his lifetime?
One example of a scientist whose work was largely ignored during his lifetime is Gregor Mendel. His experiments with pea plants led to the discovery of the basic principles of genetic inheritance, but his work was not widely recognized until after his death.
What scientist's experiment led to the discovery of protons?
There are two scientists. Goldstein is the first person that found it.
Rutherfords experiments lead to the discovery of what?
Rutherford's experiments led to the discovery of the nucleus of an atom and the existence of protons within it. By conducting the famous gold foil experiment, Rutherford concluded that atoms have a small, dense, positively charged center containing protons.
Chadwick's experiments led to the discovery of which of these?
neutrons A+
Did Thompson's experiments led to the discovery of the neutron?
no
In the late 1800s experiments using cathode ray tubes led to the discovery of the electrons?
Yes, experiments with cathode ray tubes in the late 1800s, particularly by scientists like J.J. Thomson, led to the discovery of electrons. Thomson's experiments demonstrated that cathode rays were composed of negatively charged particles, which were later named electrons. This discovery laid the foundation for modern atomic theory.
Who are the discovery of atom?
The discovery of the atom is attributed to the work of multiple scientists throughout history, such as John Dalton, J.J. Thomson, Ernest Rutherford, and Niels Bohr. These scientists made significant contributions through their experiments and theories that led to our current understanding of the atom as the basic building block of matter.
Did J J Thomson's experiments with cathode rays lead to the discovery of the neutron?
No, J.J. Thomson's experiments with cathode rays led to the discovery of the electron, not the neutron. The neutron was discovered by James Chadwick in 1932 through his experiments with beryllium.
Did Thompson's experiment led to discovery of the neutron?
no
Did Dalton model of the atoms include protons neutrons and electrons inside the atom?
no, because according to him an atom is a tiny indestructable sphere with mass on it.
Why did the atomic theory change with time?
The atomic theory changed with time as new experimental evidence and advancements in scientific knowledge challenged and refined our understanding of the structure of atoms. As technology improved, scientists were able to conduct more precise experiments that led to the discovery of subatomic particles like electrons, protons, and neutrons, which required the atomic theory to be updated to incorporate these new findings.
Who discovered tropisms?
Charles Darwin and his son did an experiment in 1880 using grass plants which led to the discovery of phototropism, this discovery led to many other scientists wanting to find out other tropisms
