What do metals have few of and form positive ions?
they have few electrons...
What is it called when you have too few electrons in an atom?
Ionization. In the issue an ion (cation) is generated.
Why is Fes unaffected by a magnet?
FeS is a compound in which iron has lost its properties so it is unaffected by a magnet.
Is the far few materials are elements than are not elements?
Very few elements exist in their free state in nature. The vast majority of them exist as compounds, chemically bonded to other elements.
Why will a lattice not conduct electricity?
to be able to conduct electricity the substance needs availably free electrons, in lattices every electron is occupied in making bonds in the lattice...hence there are no free electrons, thus it does not conduct electricity or heat with a few exceptions like graphite :) hope this info helps -melody <3
Why are some solid materials good thermal insulators while others are good conductors?
The ones that are called conductors, such as copper, and aluminum have many free electrons . free electrons are free to move from one atom to another , they are not closely tied to their nucleus. this flow is called electron drift, in other words current flow. As in a battery where the positive terminal has few electrons, and the negative has millions of electrons. attach a copper wire across them , and you have electron drift (current flow. solid materials such as rubber, plastic or porcelain or any non - metallic material are known as Insulators. They have no free electrons, thus no electron drift (current flow). an example of an insulator are rubber spacers, to make sure the motor cannot be grounded to the steel frame.
A body that has relatively few free electrons and offers comparatively great resistance to the movement of free electrons is a an?
insulator
Which is none magnetic materials?
A non-magnetic matieral is one where there are no (or very few) free electrons to conduct the electro-magnetic field. One basic example is plastic.
What is a sharing of electrons?
There are a few things that a shared pair of electrons can be called. Many people call these electrons bonded.

Why non-metal things don't attract to magnets?
There are very few non metallic materials that are magnetic or para-magnetic (attracted to magnets). The primary reason is that the outer electrons need to all spin or be able to spinn in the same direction. Only metals have appropriate electrons. That is why they are called metals.
How are n-type and p-type semiconductors similar?
N-type semiconductor materials which have free electrons,(which are negatively charged).P-type semiconductor materials which have too few electrons. Therefore the opposite of electrons - holes (which are negatively charged).You can think of it like positive and negative poles of a magnet.
What do metals have few of and form positive ions?
they have few electrons...
Why solid materials did not change their characteristic when you mixed to other solid material?
There are a few reactions wich happen between two solids. but the reason most reactions wont work between two solids is because the electrons aren't free enough to move.
What is it called when you have too few electrons in an atom?
Ionization. In the issue an ion (cation) is generated.
What materials are insulaters?
If you are talking about electrical insulators there are many types of materials. plastic, rubber, ceramic, glass, these are only a few. If you want to get into the technical aspect, it is any material that has more than four valance electrons and the more it has the better it insulates. (an electron can only have up to eight valance electrons)
Why aren't covalent or ionic compounds good conductors?
Covalent compounds are generally not good conductors because the electrons are not free to move. Solid ionic compounds are generally not good conductors because the ions are not free to move as they are locked in place in a lattice (this is not true when ionic compounds are molten or in solution!)As always there are a few exceptions, graphite is covalent but the electrons are delocalised and it does conduct, there are also a few other inorganic conductors.There are also some conductive organic polymers which have delocalised free electrons, these are called ICP's .There is also a small group of what are called fast ion conductors where the crystal structure allows the ions to wander, some are used in solid oxide fuel cells.
