Ernest Rutherford, following the "gold foil" experiment.
What else can I help you with?
How did scientist discover that atoms contained a nucleus?
Well, first of all scientific hygrenals used by scientists made it easy to discover it.
Who invented atom first?
Nobody "invented" the atom. Rather, over the course of human history, scientists have deduced the existence of atoms through observation and experimentation. Everything comes from stars, and everything goes back. nothing is wasted.
What scientist's experiment led to the discovery of protons?
There are two scientists. Goldstein is the first person that found it.
Which model of the atom first proposed that electrons orbit the nucleus?
The Bohr model of the atom was the first to propose that electrons orbit the nucleus in fixed paths or energy levels. This model was proposed by Niels Bohr in 1913, and it helped to explain the stability of atoms and the emission of specific frequencies of light.
Which came first atoms or electrons?
Of the two, electrons. (Protons had to form, perhaps from quarks, before the first atoms could form and the temperature had to be cool enough for protons and electrons to come together to form hydrogen.)
Who is a british scientists who first discovered that atoms have nucleus?
Earnest Rutherford -- A New Zealander
Who's atomic theory stated that atoms have 3 fundamental parts and the electrons orbit the nucleus?
There were many scientists that worked on trying to prove that atoms exist. Neils Bohr was one of the first to discover that atoms had three parts and the electrons orbited the nucleus in 1913.
What was the first said by scientists about atoms?
Early scientists speculated that the concept of atoms could explain the behavior of matter. The idea of atoms was proposed by ancient Greek philosophers such as Democritus around 400 BC, suggesting that matter is composed of indivisible particles. It wasn't until modern times that scientists were able to provide experimental evidence for the existence of atoms.
Who was the scientist who first proposed that electrons existed in only certain energy level about nucleus?
The scientist who first proposed that electrons existed in only certain energy levels around the nucleus was Niels Bohr. His model of the atom, known as the Bohr model, introduced the concept of quantized energy levels and provided a framework for understanding the behavior of electrons in atoms.
What scientists first proposed that the sun is the center of the solar system?
galileo
Which british scientist first disvored atoms and nucleus?
british scientist discovered the nucleus
Which scientists proposed the first formal theory of continental drift?
Alfred Wegener
Which scientist proposed that elements consisted of atoms were identical and had the same mass and that compounds were atoms from different elements combined together?
John Dalton first proposed this. Today, it's called Dalton's atomic theory.
How did scientist discover that atoms contained a nucleus?
Well, first of all scientific hygrenals used by scientists made it easy to discover it.
Would scientists come up with the cell theory if microscopes were never invented?
It is unlikely that scientists would have developed the cell theory without the invention of microscopes. Microscopes enabled scientists to observe and study cells for the first time, leading to the discovery of their fundamental properties and the development of the cell theory.
Which is first atom or element?
An atom is a single nucleus with surrounding electrons. An element is one or several atoms with the same number of protons in the nucleus.
Which scientist was the first to describe an atomic model in which most of the atom is empty space?
Ernest Rutherford was the first scientist to describe an atomic model in which most of the atom is empty space. His model proposed that atoms have a dense positive nucleus surrounded by orbiting electrons in empty space.
