Why does an ion have an electrical charge?Ions:Our Universe is composed of different types of elements and compounds. These elements and compounds are composed of atoms which are known as the building blocks of matter. An atom is electrically neutral formed with a combination of subatomic ...
If like charges repel, why does the nucleus of helium stay glued together? What happens if you keep splitting the insides of an atom? Why can atoms not be seen with a powerful optical microscope? Why are electrons allowed to fall on a crystal plate for diffraction? Why are objects with ...
Why does the atomic radii decrease as you go across a row? Explain why the exact size of an atom is difficult to determine. Why did the better part of a century pass between Thomson's work and Dalton's work? Was no one interested in researching atomic theory?
So this negatively charged particle produces an electric field around it, everywhere in space. The Electric Field is a vector quantity - it has a magnitude (how strong the field strength is) and a direction (which direction does the field point). The field strength dies off (becomes smaller ...
A material conducts heat because of free electrons present inside it. Since in insulators no free electrons are present, it cannot conduct heat.
The photons have a very high frequency, and as they travel through the medium, they emit tiny amounts of energy as they move. This energy is measured by the Coefficient of Conversion, or CoC. It is well known that as the frequency of the photons increases, so does the power of the el...
The water molecules are made up of one oxygen atom and two hydrogen atoms (H2O). Atoms have charges ‘“ a physical property which enables particles to form a bond when closed to another charged particle. In a water molecule, the oxygen atom attracts the negative charges in the hydrogen ...
What does ionizing radiation accomplish? Ionizing radiation canremove electrons from the atoms, i.e. it can ionize atoms. What is ionizing radiation? Ionizing radiation is radiation with enough energy that to remove tightly bound electrons from the orbit of an atom, causing that atom to become ...

Metals conduct electricity becausethey have “free electrons.” Unlike most other forms of matter, metallic bonding is unique because the electrons are not bound to a particular atom. This allows the delocalized electrons to flow in response to a potential difference. ...
