Is beta decay affected by Aluminum?
If you have a material that emitts Beta particles there is nothing that will effect that process. However, once the Betas are emitted you can block them with Aluminum or most anything else. How many you block will depend on how fast the Betas are going and how thick your blocking material is.
What device gives off electrons when light shines on a metal surface?
There is the photoelectric effect, which is the process that emitts electrons from a metals surface when light of a certain frequency shines on the surface. In the metal, the nuclei are surrounded by electrons, so when the incoming electrons strike the surface, they pull apart from the electrons of the metal because of how like charges detract from each other.
What are the dangers of living near volcanoes?
before a volcano erupts it emitts poisonous gases which could add to polution or destroy crops and livelyhood. also before a volcanic eruption small tremors occur around the volcano which could also damade crops and livelyhood. when a volcano doeserupt lava can be escaped from quickly and easily but ash cant. also the lava and ash would destroy your homes and lands within minutes.however they're no dangers from living near a dormant volcano.
What is the difference between a radioisotope and a normal isotope?
An isotope is one of two or more atoms with the same atomic number but different atomic weights because of having more or less neutrons. An isomer is a molecule of a compound that exists in more than one form, each form having different arrangements of atoms but the same molecular weight.
What does the sun emitt?
It emitts solar light and radiation.
What is it called when uranium turns to lead?
Uranium is radioactive. Which means its nucleus will emitt an alpha particle (two protons and two neutrons) spontaneously. Because the nucleus lost two protons it becomes the element Thorium. Thorium also emitts alpha's and changes to Radium. This process continues; Radium into Radon into Polonium and finally into lead. The final Lead is not radioactive and the process ends. The actual process is a little more complicated because some of these intermediate elements can change by converting a neutron into a proton and emitting an electron (beta radiation), but the basic process is one radioactive element changes into another radioactive element by emitting radiation (alpha's or beta's). The Uranium to Lead Process has a half-life of about 4.5 billion years. Meaning that in 4.5 billion years 1 kilogram of Uranium will have changed to a half kilogram lead and a half kilogram Uranium is still left. This is approximate because there will also be some of those intermediate elements waiting to change.
What pollutes more diesel fuel or ethanol fuel?
Diesel fuel emitts much higher emissions. It emitts high smog and particualte matter. That'll be diesal fuel darling. Madgenta
What part of the atom does nuclear radiation come from?
Light is emitted when an electron jumps from a higher energy orbit to a lower energy one. The wavelength (=colour) depends on the energy difference. Bigger is bluer, smaller redder.
What happens to a radioactive nucleus when it emits gamma ray?
It's atomic number decreases by 2 (because it has lost two protons) but as an alpha particle is two protons and two neutrons the Atomic Mass decreases by 4.
Does the moon have light and heat?
Yes and No. It reflects light from the sun, but emitts none of its own. It does not generate heat.
Which principal energy level will contain electrons with the lowest energy is what?
First energy level bc as the electron falls from high to low it emitts energy
What is the difference between a luminous objects and a illuminated object?
An illuminated object reflects light that came from somewhere else. A luminous object emitts its own light.
Why Ge and Si is not used for making LEDs?
Ge and si are not used for Making led's because these two emitts less amount in form of light and larger amount in form of heat.
Which beam should you use in the fog?
Low beam because high beam emitts too much of a pattern and basically does not help you. If you live in area that has alot of fog problems look into foglights. Also, in snow the same stands true.
How do alpha particles beta particles and gamma rays originate in the nucleus of the atom?
A beta particle is created when a neutron inside an unstable nucleus changes into a proton (or vice versa), losing energy and mass in the form of an electron (or positron), which is the beta particle.
