Floating charge

these experiments Thomson used a Cathode Ray Tube and a magnet, he placed the negative end of the magnet near the beam, and took note that when the negative end approached it, the beam deflected away. This experiment proved that there were different charges. Rutherford also employed important experiments, such as the gold foil experiment. In this experiment Rutherford shot particles at a piece of gold foil and noticed that while most of the particles passed through the foil there were some that…

Chemical changes are everywhere from everyday things such as baking to scientific things such as changing one gas into another. Physical changes are changes that can be observed with senses and change a certain property or properties to a substance but it still remains chemically the same. This can include changes in the state of matter, size and shape. Chemical changes are when the substance is changed chemically with its properties changing with it. The substance with change from one substance…

“Steel plates are commonly attached to each other with rivets, which are slipped into holes in the plates and rounded over with hammers. The hotness of the rivets makes them easier to round over, but their hotness has another important advantage in providing a tight fit. What is it? Explain why.” This relates to one of the characteristics of heat, in that heated objects expand, then contract when the temperature decreases, since the molecules move faster in heat and slow in the cold. The hot…

This essay going to be about an atom. Atom is always around us all the time and ever object are made out of an atom. We, humans, are also made of the atom. Knowing about the structure and what it really is a very important thing to learn as a student. In order to learn about an atom, we will have to understand about Democritus first. So who is Democritus? Democritus is the first human to ever come up with the first atomic theory. Democritus was born in Greece around 460BC. He has a life spend…

AC stands for alternating current which means that the current flows in both directions. So instead of flowing from one source to another, the current can flow from both the source and the recipient to each other. AC voltage is the current that comes from an electrical plug. An advantage of AC voltage is the fact that the power of the voltage can be altered with a transformer. Fig.1 graph showing AC and DC current On the other hand DC voltage stands for direct current. This means that the…

So also, nonmetals that have near 8 electrons in their valence shells tend to promptly acknowledge electrons to accomplish honorable gas arrangement. In ionic holding, more than 1 electron can be given or got to fulfill the octet run the show. The charges on the anion and cation relate to the quantity of electrons gave…

Atoms, ions, and isotopes are everything you eat, breathe and see. They are everywhere and everything is made up of them. The first person that aided in the discovery of the atom was Democritus in 400 BC. He is the one that named the atom. The word atom comes from the Greek word atomos which means indivisible. Aristotle which was another flossier in at that same time disagreed with him. He believed that matter could be divide infinitely without changing its properties. At that time more people…

When two or more atoms chemically bond with each other, the resultant chemical structure is a molecule. The familiar water molecule, H2O, consists of two hydrogen atoms and one oxygen atom, which bond together to form water . Atoms can form molecules by donating, accepting, or sharing electrons to fill their outer shells. These processes go under Covalent or Ionic bonding. A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. It only happens between…

Arya Marwaha Life Science Mrs. Conklin October 11, 2016 Science Fair Outline Introduction I will be testing if different fruits and vegetables can conduct enough power to create electricity This question can help save electricity and offer a new way to conduct power. It is also an interesting topic to test on. The hypothesis states that different produce can conduct enough power to create electricity, because Zinc and Copper (the two elements I am testing) have a certain relationships with…

Q. Why do wire and a compass work to detect electric currents? A. I’m going to start off with the basics here. A compass points north. Everyone knows that. Why does it point north? Well, all magnets have two “poles” or ends. One end of the magnet is called the north-seeking pole. The north-seeking pole is often abbreviated to north pole or the letter N. The north pole end of a magnet is usually colored red. The other end of a magnet is called the south-seeking pole. The south-seeking pole is…
