Rutherford proposed that atoms have a dense, positively charged nucleus surrounded by negatively charged electrons orbiting the nucleus like planets around the sun. This led to the development of the planetary model of the atom.

What did Pythagoras say about atoms?

Pythagoras did not specifically discuss atoms, as the concept of the atom was developed by later philosophers like Democritus. Pythagoras focused on geometry, mathematics, and the concept of numbers as the essence of reality.


How can we say that air is a matter?

Air is considered matter because it has mass and occupies space. It is composed of molecules and atoms, just like other forms of matter. Air can be compressed or expanded, and it interacts with other substances, demonstrating its physical properties as matter.


How do you know what the atom looks like when no one has ever seen it?

You don't really know what it looks like. What's more, an individual atom doesn't "look like", because it is much smaller than the wavelength of visible light. What the models used to describe the atom really say is that the atom "behaves as if..." such-and-such.


How do molecules say together?

Assuming you meant 'stay' and not 'say' then the answer would be bonds. Atoms within a molecule are bonded together by either covalent or ionic bonds depending on the difference between their negativities. For instance, NaCl, commonly known as table salt, is an ionic bond while CO2 is a covalent bond. A rule of thumb is that if the two atoms are the same time (IE nonmetal or metal) then they are covalent.


What does it mean to say that a physical quantity is quantized?

Quantized means that the physical quantity can only take on certain specific values, and not any value within a continuous range. This is often seen in phenomena like energy levels in atoms or the quantization of angular momentum in quantum mechanics.

There are no images of his father. There is a picture of a relative that they say looked just like him in the museum in Fremont Ohio. There is one picture (at least) of his mother there.


Why did Rutherford say that bombarding atoms with particles was like playing with marbles What subatomic particle did Rutherford discover during this phase of his work?

Rutherford compared bombarding atoms with particles to playing with marbles because, just as marbles can bounce off each other or collide in unpredictable ways, particles striking atoms can lead to various outcomes, such as deflections or reactions, revealing the structure of the atom. During this phase of his work, Rutherford discovered the nucleus of the atom and identified the proton as a subatomic particle, fundamentally altering our understanding of atomic structure.


What did democritus say about the atom?

To Democritus the atom looked like a marble. Democritus theorized that matter could only broken down into pieces of a certain size. These pieces which could not be broken any further were called atoms.

What did Rutherford say about the small number of particles that bounced straight back?

Rutherford fired alpha particles at a sheet of atoms in order to determine the atomic structure. The alpha particle is positively charged. Those particles that bounce straight back are the ones that hit the nucleus of the atom and were repelled by the nucleus's positive charge.

Why did Rutherford say the deflection of an alpha particle was like?

Rutherford said the deflection of an alpha particle was like firing a bullet at tissue paper and having it bounce back. This analogy conveyed the unexpected result that particles were being deflected backwards, suggesting the presence of a concentrated positive charge in the atom's nucleus.
