Thomson also knew that atoms are electrically neutral, meaning that they have no overall charge. He reasoned that there must be some positive charge in atoms that cancels out the negative charge of the electrons. He also followed the work of William Thomson (Lord Kelvin), who had proposed a...
How can a charged atom (an ion) attract a neutral atom? If a neutral atom loses an electron what is formed? Define an ion. Explain why an ion will form. Cations are formed when neutral atoms lose How does an atom become a positively charged ...
All atoms have moving electric charges. Then, why aren't all materials magnetic? Explain how charging by induction happens in a neutral sphere and balloon experiment. There are very large numbers of charged particles in most objects. Why, then, don't most objects exhibit static electric...
The read-write heads are mounted on an electrically controlled arm that moves from the center of the drive to the outer edge and back again. To reduce wear and tear, they don't actually touch the platter: there's a layer of fluid or air between the head and the platter surface....
When we switch on the power, the copper sulfate solution splits into ions (atoms with too few or too many electrons). Copper ions (which are positively charged) are attracted to the negatively charged brass electrode and slowly deposit on it—producing a thin later of copper plate. Meanwhile...
Explain how charging by induction happens in a neutral sphere and balloon experiment. All atoms have moving electric charges. Then, why aren't all materials magnetic? Why do like magnetic poles repel each other? What is the origin of this ...
When U238 decays into Pb206 via alpha and beta decay, what are the byproducts of the decay? A) 8 alpha particles and 6 beta rays B) 8 alpha particles, 6 electrons, 6 neutrinos, and energy C) 16 alpha An atom is normal...
Ionic compounds are made up of electrically charged particles, Why does not such a compound have an overall electric charge? A dish has 10 + charges and 10 - charges. 2 of the negative charges are taken away. What is the overall charge? Define (a) a coulomb,...
