Which atom in ClF is more negatively charged? Why do the oppositely charged plates of a capacitor attract each other? Explain what is electric potential and its basic properties. At the atomic level, what is meant by saying, "something is electrically charged"?
The smallest unit of any matter is known as an atom. Any matter is formed by the number of atoms binding together. Every matter, such as solid, liquid, and gas, contain neutral or ionized atoms. The diameter of the atom is in the pico-meter range. ...
Protons and neutronscan move around a bit within the nucleus, depending on the nucleus. They also vibrate, so they're never 'completely stationary'. Nor do they move on the scale of the atom, which is something that's about 10,000 times larger than the nucleus. What is inside a neutron?
Producing hydrogen takes energy because hydrogen atoms don't exist on their own — they are almost always stuck to another atom, often another element. (On earth, hydrogen is particularly abundant in the form of water, or H2O.) Creating pure hydrogen requires breaking those molecular bonds. In...
Neurons are small, but we know how to split an atom. A neuron’s diameter is about 100,000 times as large as an atom’s—if an atom were a marble, a neuron would be a kilometer across—so we should probably be able to handle the smallness. Right? So what’s the issue here?
