Why does rutherford's gold-foil experiment conclude that the atom is mostly empty space with a small massive positively charged center?
because few particles bounced back
How did Rutherford know an atom was mostly empty pace?
Most of his test particles (alpha particles) when straight through.
Is a tornado a form of matter?
A tornado is made of matter, mostly air, but it is not a special form of matter.
What do charged particles from the sun that get close to the earths surface produce?
The solar wind is a stream of charged particles ejected from the upper atmosphere of the Sun. It mostly consists of electrons and protons with energies usually between 10 and 100 keV. The stream of particles varies in temperature and speed over time. These particles can escape the Sun's gravity because of their high kinetic energy and the high temperature of the corona.The solar wind creates the heliosphere, a vast bubble in the interstellar medium that surrounds the solar system. Other phenomena include geomagnetic storms that can knock out power grids on Earth, the aurorae (northern and southern lights), and the plasma tails of comets that always point away from the Sun.
What did Rutherford discover about atom structure?
Rutherford oversaw the gold foil experiment. This experiment showed that the atom is mostly empty space and that most of its mass is concentrated in a tiny central core called the atomic nucleus.
What is the basis of a structure of an atom?
The basic structure of the atom has a nucleus in the center which contains protons (positively charged particles), and neutrons (neutral particles). Around the nucleus are the electrons (negatively charged particles). The atom is mostly empty space with very little mass.
What is a materials that does not let electricity flow through it?
Many materials are packed full of easily-movable charged particles. Any material that does not contain easily-movable charged particles is called an "insulator". Charged particles do not flow through an insulator. Common insulators are rubber, plastic, nylon and air. (Rubber, plastic, and nylon are packed full of charged particles, but those particles are "bound" into a solid, unmoving configuration. The particles in air are easily-movable, but they are practically all uncharged particles -- and also there are so few of them that air is mostly empty space compared to solids).
Why are there electronic charges?
Because the entire universe is made up (Mostly) of positively and negatively charged sub-atomic particles.
What particles are in space?
There are little particles in space that came off of meteroroids.
What are the major properties of soil?
Sand, soil, clay particles, and organic matter that mostly comes from decaying plant materials.
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)
What were the conclusion of Rutherford alpha particles scattering experiment?
He observed that alpha particles can scatter (bounce) backwards off of matter. If matter was evenly distributed, the high energy particles should go through it like "a 15 inch shell through tissue paper" to paraphrase Rutherford. The fact that they bounced back meant that the charged matter (protons) must be distributed in small dense clusters so that the alpha particles (helium nuclei) hit these charges like a billiard ball and, if hit directly, could bounce straight back. This lead him to the understanding that atoms have a small central charged nucleus surrounded less densely by negative charges (electrons). It was, in some sense, the end of nuclear physics.

What are the Auroras caused by?
Caused by the collision of charged particles directed by the magnetic field of earth. Mostly common in polar regions auroras are good astronomical sight at night.
What was Ruthford's hypothisis on his Gold Foil experiment?
Atoms are mostly empty space with a very, positively charged nucleus. Alpha particles are one of the biggest as far as radiation goes. (:
What is the difference between the top soil in the desert and the grassland?
Desert soils are mostly composed of minerals - finely divided rock particles and have little organic matter. Grasslands have much more organic matter.
How did gold foil experiment show that there is a nucleus in the atom?
The gold foil experiment showed that there is a nucleus by how the alpha particles(positively charged particles) were deflected and changed course by the foil. It showed that the atom is made of mostly empty space because most particles went through the foil. Some of the particles though were deflected to the sides of the container around the foil and some where even reflected back at the light almost. Rethurford (or however you spell is name lol search it) theorized that there is a small nucleus that is positively charged that some particles came close to and were deflected away because the nucleus had an effect on them. Some particles hit the nucleus exactly and were reflected back only because it was positively charged if it had been negativly charged it wouldn't have went back to the light.
