What did the scientist say about the structure of an atom, stating that it is mostly empty space?
The scientist stated that the structure of an atom is mostly empty space.
Which scientist first stated the relationship between buoyant force and weight of a displaced fluid?
Archimedes first stated the relationship between buoyant force and weight of a displaced fluid.
Which scientist first stated the relationship between bouyant force and weight of a displaced fluid?
Archimedes was the scientist who first stated the relationship between buoyant force and weight of a displaced fluid. He discovered the principle while trying to determine if a gold crown was made of pure gold.
Using heisenberg's uncertainity principle prove the non existence of the electron inside the nucleus?
The Heseinberg's Uncertainty Principle states that you cannot know the position and momentum of a particle simultaneously. More rigorously stated, the product of the uncertainty of the position of a particle (Δx) and the uncertainty of its momentum (Δp) must be greater than a specified value: ∆x∆p ≥ (h/4π) Now, as the electron approaches the nucleus, it's uncertainty in position decreases (if the electron is 10nm away from the nucleus, it could be anywhere within a spherical shell of radius 10nm, but if the electron is only 0.1nm away from the nucleus, that area is greatly reduced). According to the Heisenberg uncertainty principle, if you decrease the uncertainty of the electrons position, the uncertainty in its momentum must increase. This increased momentum uncertainty means that the electron will be moving away from the nucleus faster, on average. Put another way, if we do know that at one instant, that the electron is right on top of the nucleus, we lose all information about where the electron will be at the next instant. It could stay at the nucleus, it could be slightly to the left or to the right, or it could very likely be very far away from the nucleus. Therefore, because of the uncertainty principle it is impossible for the electron to fall into the nucleus and stay in the nucleus. In essence, the uncertainty principle causes a sort of quantum repulsion that keeps electrons from being too tightly localized near the nucleus.
This scientist first published a document that stated that every particle in the universe is attracted to every other particle with a force that is directly proportional to the product of their masses?
The scientist you are referring to is Sir Isaac Newton. This statement you mentioned is based on his law of universal gravitation, which was published in his work "Philosophiæ Naturalis Principia Mathematica" in 1687. It is one of the fundamental principles in classical physics.
Who said electron paths cannot be predicted and when?
Schrodinger and Heisenberg state that electrons cannot be predicted in 1927. It was stated that the more precisely the position of some particles are determined, the less precisely its momentum can be known.
What scientist stated evolution?
Darwin
What is the ground stated electron configuration HE?
2
Who stated that you can't know the exact position of an electron?
Heisenberg
Who stated that everything is composed of atoms?
The scientist who stated that everything is composed of atoms was Democritus, an ancient Greek philosopher.
What famous scientist stated that the solar system is heliocentric?
Nicoli Copernicus.
Which famous scientist stated the law of gravity?
sir isaac newton
What scientist stated that planets move around the Sun in an ellipse?
Kepler
Which model of the atom states that the position and location of an electron cannot be known with certainty but only stated as a probability?
The quantum mechanical model of the atom, also known as the electron cloud model, states that the position and location of an electron cannot be precisely determined but rather described in terms of a probability distribution within an atomic orbital. This model was developed based on the principles of quantum mechanics to better explain the behavior of electrons in atoms.
What did the scientist say about the structure of an atom, stating that it is mostly empty space?
The scientist stated that the structure of an atom is mostly empty space.
This scientist stated the law that a force was needed to change an objects motion?
Issac Newton.
What scientist first stated that the paths of planets are ellipses instead of circles.?
Johannes Kepler
