ReneIn the Geiger and Marsden experiment, alpha particles were fired at a thin gold foil. They observed that while most alpha particles passed straight through, some were deflected at large angles and even back towards the source. This led to the conclusion that the majority of the atom's mass is concentrated in a small, positively charged nucleus, causing the deflections.

Who used the gold foil experiment to determine the atom is mostly empty space?
Ernest Rutherford used the gold foil experiment to determine that the atom is mostly empty space. He directed alpha particles at a thin sheet of gold foil and found that while most particles passed through, some were deflected, leading him to conclude that atoms have a small, dense nucleus surrounded by mostly empty space.
What instrument measures radiation?
Geiger Counter, named after Hans Geiger, who developed the device in 1908. There are several others, Crystals that emit light when exposed to radiation are coupled to photoelectric tubes and the light out-put of the crystal is a measure of the radiation absorbed by the crystal. Gas filled ionization chambers which operate much like a Geiger counter are another. Thermoluminescent materials, photographic (x-ray) film, cloud chambers, and bubble chambers are a few others.

What type of star alpha?
There is no "star alpha". Alpha is PART of the name of many stars - basically one for each constellation.
Which star is bigger the alpha centauri or the sun?
Alpha Centauri is actually a binary star system consisting of two stars, Alpha Centauri A and Alpha Centauri B. Alpha Centauri A is slightly larger than the Sun, while Alpha Centauri B is slightly smaller.
How many Satellites does Alpha Centauri have?
As of current knowledge, there are no known satellites orbiting Alpha Centauri, which is our closest neighboring star system. However, further exploration may potentially discover any satellites that might exist.
