How does reactivity work with the elements going down the groups for metals and non metals?
Reactivity increases down the group for metals. It decreases down the group for non-metals.
Classes of elements?
Metals, non metals and metaloids (which have some of the properties of both metals and non metals).
Are metalloids metals non metals the same?
They are in between the metals and non metals
What makes silicon a semiconductor?
Elements have two bands. One is Valence band and other is Conduction band. Valence band contains electrons whereas the conduction band is empty. The energy gap between them is called the forbidden gap. In case of metals, this gap is very small or the bands overlap. Therefore, the electrons are able to jump from the valence band to the conduction band and hence metal are able to conduct electricity and they are generally conductors. In case of Non-Metals, the energy gap is very large and hence hence electrons are not able to move from valence band to conduction band. Hence they are insulators. But in case of elements like Silicon, Germanium this gap is between Metals and Non-Metals, hence few electrons are able to move from valence band to conduction band. Therefore they have some conductivity but it is low and hence they are called semiconductors.
Are tent poles made out of non metals or metals?
non metals
How does the electrical and heat conduction of metals and non metals compare?
Electrical and heat conduction is much greater in metals than in non metals.
What type of substance does conduction work best in?
Conductors of electricity are usually metals although there are a few cases where non metals are conductors as well such as graphite and types of salt solutions, hope this answers your question.
What is the conduction of metal?
The conduction is transfer of heat between metals,also called metallic conduction
What are the similarities and differences between metals and metalloids and non metals?
The electrons in a metal can leave the atom and move about in the metal as free electrons. While atoms in non-metals are bonded. Heat energy is passed along by vibartions as the bonds between the non-metals atoms are shaken. Conduction in metals is faster than in non-metals. Making metals good conductors and making non-metals poor conductors.
How does conduction take place in non metals?
conduction takes place in a non metal by vibrating particles hopefully this helped, its just a short sentence that summed it up really good luck! if your doing a test lol
Does conduction Happen better in metals or plastics?
Electrical conduction in metals nearly always (you can have conducting polymers keep in mind)
What elements are nonconducting?
if you mean the conduction of electricity then.... all non-metals do not conduct(excluding carbon which does conduct) all metals conduct although some conduct better than others
Heat conduction is most efficient in metals nonmetallic metals water or gases?
metals
Heat conduction is most efficient in?
Heat con conduction is efficient metals
what does metallic consist of?
Metals have large number of free electrons, which are responsible for conduction of heat, electric current, etc. Hence metals are good conductors. Non-metal don't have such free electrons in them. Hence they are bad conductors. There are many such properties which differentiate metals from non-metals. for example, metals have a typical metallic luster ( except few), etc.
How can conduction be helpful?
Conduction can cause a spark which can light a light bulb. Conduction can be used to heat up metals.
Is metals and iron and gold a conduction?
yes
