What else can I help you with?
Most atoms are composed of electrons protons and neutrons. Which particles are found in the nucleus of a gold atom?
Not just "most" atoms , but all atoms are composed of protons and neutrons, which are found in the nucleus, and electrons surrounding the nucleus in the electron cloud. And these atoms include gold.
What did Rutherford gold foil experiment suggest about the structure of an atom?
1) Atoms were mostly empty space (because most alpha particles went straight through the gold foil) 2) Atoms had a dense nucleus (because few alpha particles bounced straight back from the atoms) 3) The nucleus of atoms were positively charged (some alpha particles were deflected at large angles)
Which two subatomic particles make up most of the atoms mass Where are they located?
These particle are neutrons and protons; they are located in the atomic nucleus.
In Rutherfords gold foil experiment shown in Figure 4-1 alpha particles that bounce straight back from the foil have struck in the gold atoms?
No, they struck the nucleus of the atom. Since the alpha particles are positively charged and nucleus is positively charged as well, they repelled each other and alpha particles are repelled back
What is the most of the mass of an atoms?
The nucleus.
Rutherfords gold foil experiment led to the discovery of the?
Nucleus - Rutherford fired particles at gold foil, and most went straight through. This showed that most of atoms are empty, and that most of the mass only occupies a small part of the atom. This part is known as the nucleus.
Most alpha particles passed directly through the gold atoms undisturbed what does this evidence suggest about the structure of the gold atoms?
The fact that most alpha particles passed directly through the gold atoms suggests that the majority of an atom's mass is concentrated in a small, dense nucleus. This implies that the rest of the atom consists of mostly empty space with electrons moving around the nucleus.
Why do atoms have no electric charge even though most of the particles inside the atoms have charges?
Because the positive charge of the protons in the nucleus is exactly canceled by the negative charge of the electrons in the orbitals around it.
What was Ruthford's hypothisis on his Gold Foil experiment?
Ernest Rutherford's hypothesis for his Gold Foil experiment was that atoms have a dense positive nucleus at their center and that most of the atom's mass is concentrated in this small nucleus. He proposed this after observing the scattering pattern of alpha particles in the gold foil.
Which particle is not found in the nucleus?
Atoms are the building blocks of matter. Atoms are made up of electron, neutron and proton particles. Electrons are negatively charged, neutrons are neutral and protons have a positive charge.
What does most of the atoms mass come from?
the nucleus
Where is most of an atoms mass?
Inside the nucleus.
