Briefly and clearly explain why charged objects attract neutral objects. "In the Compton effect, however, the electron can be free". Explain. If atoms exist, why can't we see them with visible light? Why don't electric charges always follow the electric lines of force?
Why can't atoms gain or lose protons? Why don t atoms gain or lose protons?Atoms never gain protons; they become positively charge only by losing electrons. A positive ion is called a cation (pronounced: CAT-eye-on). You may have notice that the number of neutrons in each of these io...
In chemistry, the noble gases are stable and seldom react to other chemical elements. Explore why noble gases don't bond, learn that they are non-reactive gases, recognize where they're found, and understand how they're used in everyday life. ...
Briefly and clearly explain why charged objects attract neutral objects. Insulators also contain electrons, but they are not conductors, Why? Why does a negative charge move from low to high potential? Why is an electric current a fundamental quantity instead of the charge that gives...
Arrhenius theory, theory, introduced in 1887 by the Swedish scientist Svante Arrhenius, thatacids are substances that dissociate in water to yield electrically charged atoms or molecules, called ions, one of which is a hydrogen ion (H+), and that bases ionize in water to yield hydroxide ions ...
Luckily, many atoms, including hydrogen and anti-hydrogen, have a “magnetic moment”. While they are electrically neutral and unresponsive to electric fields, they do act like little bar magnets and we can use that to keep them suspended. Even so...
it is as if someone were sticking their fingers in their ears while they are crowing. The researchers noted the birds also have another advantage—unlike humans,birdscan regrow damaged hair cells. As for why the hens and chicks do not suffer hearing damage from the male crowing, though not ...
The offspring of older mothers don't fare as well as those of younger mothers, in humans and many other species. They aren't as healthy, or they don't live as long, or they have fewer offspring themselves. A longstanding puzzle is why evolution would mai
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. ...
Neutral atmosphere Below about 100 km, or about 60 miles. (See the onlinedistance converter) Ionosphere Above about 100 km. Contains electrically charged particles or ions, created by the absorption of UV (ultraviolet) light. The degree of ionization varies with altitude. ...
