I'm doing an assignment for grade 8 science in which I have to prove whether or not atoms are fact or fiction. I was just wondering if anyone would be able to give me a few tips to help me out with this.
In addition to the previous recommendation, you might also want to look up the Rutherford scattering experiment. This experiment not only confirmed the existence of atoms (which was already generally accepted), it confirmed that atoms have the internal structure of a heavy positively charged nucleus concentrated in a small volume compared to the size of an atom.ShadowChaotic said:I'm doing an assignment for grade 8 science in which I have to prove whether or not atoms are fact or fiction.

Atoms are made up of three subatomic particles: protons, neutrons, and electrons. Protons and neutrons are located in the nucleus of the atom, while electrons orbit the nucleus in energy levels.
No, atoms cannot be seen with the naked eye. They are incredibly small, with a diameter of around 0.1 nanometers, making them impossible to see without the use of specialized equipment such as an electron microscope.
There are currently 118 known types of atoms, known as elements. These elements are listed on the periodic table, which arranges them according to their atomic structure and properties.
Yes, atoms are constantly in motion. This movement is known as Brownian motion and is caused by the random collisions between atoms and molecules. The speed of this movement is affected by factors such as temperature and pressure.
Yes, atoms can combine to form molecules through chemical bonding. This occurs when atoms share, gain, or lose electrons to achieve a stable outer electron configuration. This bonding creates new substances with unique properties.
