A shortage of electrons on a surface creates an electric what?
A shortage of electrons on a surface creates an electric what?
The magnetic domains are two regios of space above Earth's surface that contain electrons and protons thraveling at high speeds?
Van Allen belts
A shortage of electrons on surfaces create what kind of charge?
A shortage of electrons on the surface create positive charge. Because aall bodies in nature remains electrically neutral. But we know that electrons are negatively charged particles. It means if there is deficiency of electrons at any surface there would be positive charge. Which means electrons are less than protons which are positively charged particles and hence causes positive charge on surface.
What can be found in an atom's nucleus?
The nucleus can be found in the center of an atom. The electrons can be found in the 'surface' if an atom is considered to be a sphere.
What are free electrons of conductor?
First we have to define the word an electron, An electron is negatively charged particle. A metal is a substance consists of number of both electrons and protons. Electrons emitted from the metal surface through different ways such ways as Thermionic, Photoelectric, etc. Free electrons of conductor are electrons emitted from conductor when it disturbed through ways as mentioned above
What happens when you are within a few miles of the surface of the Sun?
It is so hot (6000K) that you will be turned into plasma (the atoms of your body will disassociate into electrons and the nuclei (protons and neurons)You go *poof* into ash.
Is there any material which can withstand the temperature of the surface of the Sun?
The only thing that would not be instantly vaporized is the basic stuff of matter, protons, electrons, neutrons, elements etc.
What is the emission of electrons from a metals surface?
the external energy given to electrons,thier kinetic energy increases.thus electrons move from metal surface
What is a electronic scan?
The scanning electron microscope (SEM) is a type of electron microscope that images the sample surface by scanning it with a high-energy beam of electrons in a raster scan pattern. The electrons interact with the atoms that make up the sample producing signals that contain information about the sample's surface topography, composition and other properties.
