Which scientist using the gold foil experiment isolated the nucleus in 1911?
Ernest Rutherford is the scientist who conducted the gold foil experiment in 1911 and discovered that atoms have a small, dense nucleus at their center. This experiment led to the isolation and identification of the atomic nucleus.
Who discovered the nucleus using his gold foil experiment?
Ernest Rutherford is the scientist who discovered the nucleus through his gold foil experiment in 1909. He observed that most of the alpha particles passed through the foil, but some were deflected, leading him to propose the existence of a dense, positively charged nucleus at the center of an atom.
Who discover the nucleus using the alpha particles bombarded into the gold leaf?
Ernest Rutherford discovered the nucleus by conducting the famous gold foil experiment in 1909. He bombarded alpha particles onto a thin gold foil and observed that some particles were deflected, leading him to conclude that atoms have a dense nucleus at their center.
Rutherford's gold foil experiment provided evidence for what?
In 1911, Rutherford decided to experiment using what was the current theory of atomic structure at the time. Based on his results, he proposed a new theory; that the majority of the atom is empty space, and that all of the positive and most of the mass are contained in a small central region within the atom, which became later known as the nucleus.
An experiment using alpha particles to bombard a thin sheet of gold foil indicated that most of the volume of the atoms in the foil is taken up by?
a small, dense, positively charged nucleus. This led to the discovery of the atomic nucleus and the development of the nuclear model of the atom.

Who discoveredthe nucleus using his gold foil experiment?
Rutherford
Who discovered tropisms?
Charles Darwin and his son did an experiment in 1880 using grass plants which led to the discovery of phototropism, this discovery led to many other scientists wanting to find out other tropisms
Who discovered change of electron by oil droplet experiment?
Robert Millikan discovered the change of electron using the oil drop experiment in 1909. He was able to measure the charge of an electron accurately using this method.
What describes the correct order for using the scientific?
A scientists should form a hypothesis, then conduct an experiment.
Who discover the nucleus using the alpha particles bombarded into the gold leaf?

Can the nucleus be discovered using analytical cell fractionation?
Peroxisomes, Lysosomes, E.R., and the Golgi Apparatus.
Why did scientists know that atoms have positive charges?
A neutral atom has not an electrical charge; only cations have a positive charge. Using an electrochemical cell with two electrodes (anode and catode) you can determine the charge of ions in the solution.
What scientist said most of the mass of the atom is in tiny dense positively charged nucleus?
Ernest Rutherford is the scientist who proposed that most of the mass of an atom is concentrated in a small, dense, positively charged nucleus, based on his gold foil experiment which led to the discovery of the atomic nucleus.
Scientific method examples?
SCIENTIFIC METHOD is a process and principles that guides scientific investigations. It is defined as the making of careful observation and experiments and latter using the data obtained to formulate general principles. The scientific method begins with recognizing problem. Usually curiosity helps us recognize problem. Second, the scientists gathers and organize the data regarding the problem. In this way, instead of discovering things already discovered, the scientists utilizes the work of preceding scientists. This is how science progresses. Third, the scientists attempts to explain the phenomenon in a working hypothesis. The hypothesis is made even before an experiment is made. Fourth, he plans experiment to test the validity of the hypothesis. If the experiment supports the hypothesis, the scientists then can formulate a more definite theory to explain the observe facts.
What was Millikan able to determine about electrons through a series of experiments?
Millikan discovered that electrons had a negative charge using his Oil Drop experiment.
