How did Rutherford come to the conclusion that the space occupied by the nucleus is very small and the atom is almost all empty space?
Rutherford came to this conclusion after his Gold-Foil experiment. He found that most of the alpha particales(when released) went straight through the gold foil of which consisted of atoms. In the middle of the atom theres a small nucleus that has mass and positive charge. Because the nucleus is so small the alpha particles were able to go straight through leading to the conclusion that atoms are mostly empty space.
so why did he do the gold-foil experiment?
What else can I help you with?
What conclusion is based on the gold foil experiment and the resulting model of the atom?
The conclusion from the gold foil experiment led by Rutherford is that atoms have a small, dense, positively charged nucleus at their center, with electrons orbiting around it in a mostly empty space. This model of the atom overturned the plum pudding model and established the foundation for our current understanding of atomic structure.
Describe Rutherford's Model of the atom?
Rutherford's model of the atom consisted of a positively charged center, known as NUCLEUS, which also contained most of the atom's mass. Around the nucleus orbited the negatively charged electrons.
What was discovered first nucleus electron proton neutron?
Electron was the first subparticle discovered because it has a negative charge .later protons where discovered because using the foil method determined the protons existence .But because the neutrons are neutral and uncharged they where the last to be dicovered even though they take up almost all the mass of an atom
What parts of an atom makes up all the mass of an atom?
The nucleus is the part of an atom that contains practically all its mass. In the nucleus, you can find the proton and neutron. The number of electrons, which move about the nucleus, is equal to the number of protons.
Who identified the nucleus of an atom?
The nucleus of an atom is far too small to be "seen" in any conventional sense. The structure of the atom, that is, the one with most of the mass of the atom concentrated in the center, or nucleus, was developed by physicist Ernest Rutherford. In a sense, he is the one who first "saw" the nucleus of the atom. A link to the Wikipedia article on the atom, an article which includes the history of discoveries that lead to modern concepts of it, is provided. A link is also provided to the Rutherford model of the atom, also at Wikipedia. Hey, the nice folks at Wikipedia post knowledge for free. Why not surf on over and help yourself? It's a buffet, with all you can eat.
Rutherford said that almost all the mass of an atom is located in its what?
Rutherford discovered in the early 1900s that most of an atom's mass is located in its nucleus.
Did bohr discover that the atoms mass came frome neutrons and protons?
Rutherford discovered that almost entire mass of an atom is located in the nucleus, and then, the neutron was discovered by Chadwick.
What conclusion is based on the gold foil experiment and the resulting model of the atom?
The conclusion from the gold foil experiment led by Rutherford is that atoms have a small, dense, positively charged nucleus at their center, with electrons orbiting around it in a mostly empty space. This model of the atom overturned the plum pudding model and established the foundation for our current understanding of atomic structure.
Who discover the nucleus?
The nucleus is the very dense region consisting of nucleons (protons and neutrons) at the center of an atom. Almost all of the mass in an atom is made up from the protons and neutrons in the nucleus, with a very small contribution from the orbiting electrons. It was discovered in 1911, as a result of Ernest Rutherford's interpretation of the famous 1909 Rutherford experiment performed by Hans Geiger and Ernest Marsden, under the direction of Rutherford.The diameter of the nucleus is in the range of 1.75 FM (1.75×10−15 m) for hydrogen (the diameter of a single proton)[1] to about 15 FM for the heaviest atoms, such as uranium. These dimensions are much smaller than the diameter of the atom itself (nucleus + electronic cloud), by a factor of about 23,000 (uranium) to about 145,000 (hydrogen).
How is the Rutherford Experiment Done?
To do the Rutherford Experiment, you have to shoot alpha particles at gold foil to and see where the particles pass through and where they do not. This will give you a general idea of what Rutherford did to discover the nucleus of an atom. However, alpha particles are very hard to come upon, as they are the nucleus of Carbon. Rutherford knew that alpha particles are about 7000 times more massive than electrons and are positively charged and the charge is twice the magnitude of the charge of electrons.when Rutherford directed a beam of alpha particles at a thin gold foil,he found that almost all particles passed through it without deflecting.A very small were deflected at an angle, however, and a few actually bounded back toward the particle source.
Describe Rutherford's Model of the atom?
Rutherford's model of the atom consisted of a positively charged center, known as NUCLEUS, which also contained most of the atom's mass. Around the nucleus orbited the negatively charged electrons.
Lost of an atoms mass is in the nucleus?
Almost all of an atom's mass is in the nucleus.
Which region was occupied by Germans?
During WW2 the Germans occupied almost the entire continent of Europe except for Spain and Portugal.
What was discovered first nucleus electron proton neutron?
Electron was the first subparticle discovered because it has a negative charge .later protons where discovered because using the foil method determined the protons existence .But because the neutrons are neutral and uncharged they where the last to be dicovered even though they take up almost all the mass of an atom
Is a nucleus found in plant cell?
Yes, almost all living cells have a nucleus.
What parts of an atom makes up all the mass of an atom?
The nucleus is the part of an atom that contains practically all its mass. In the nucleus, you can find the proton and neutron. The number of electrons, which move about the nucleus, is equal to the number of protons.
Who is Rutherford and the gold foil experiment?
Rutherford was a scientist who shot alpha particles through a very thin sheet of gold foil. The results of this experiment are the following: -Almost all alpha particles passed right through the Gold foil -A few alpha particlas were deflected and repelled .....These conclusions show that the majority of the atom of gold is empty space except for a small, positively charged nucleus. This nucleus is the reason why some alpha particlas were deflected(Alpha particles have a positive charge, which is repelled by a positive nucleus).
