Materials with many free electrons are considered what?
Electrical Conductor
Why do solid and liquid metals conduct electricity?
Graphite, an allotrope of carbon, is classified as a semimetal, that is, a material that shares some of the properties of metals. Many other non-metallic materials conduct electricity; including salts, plasma and some polymers.
Why are metals better conductors of electricity than glass or ceramic materials?
it is because wood is not a better insulator metal heats up faster depending on the metal. suppose you are heating up aluminum, it would heat up faster because there are more free electrons so it can transfer heat faster.
How does light transmit through matter?
There are few electrons in shells (electron shells are energy levels) that scatter photons in transparent matter, In metals there are many so metals are opaque and they also can reflect light (the photons "bounce" off the metal surface).
What makes metal a good conductor?
Because the atoms of a metal form a "regular" matrix through which their outer electrons can move freely.The attraction between one atom's nucleus and a neighboring atom's electrons packs the atoms closely together. This close packing causes the outermost energy levels of the atoms to overlap. Therefore, electrons are free to move from atom to atom.Metals as a group are pretty good conductors of electricity. Silver, copper, gold and aluminum top the list, but the reason metals conduct electricity can be explained in one of two ways. The fundamental reason that is often cited is that metals have a large number of free electrons that will support current flow. Apply a voltage, and the free electrons begin moving and current flow is almost instantaneous.Another idea that might explain the issue is that for a given material, there is a minimum energy that electrons in that material must have to support current flow. This is the minimum energy of what is called the conduction band for that material. In metals, there already are a large number of electrons that are in the conduction band. The "natural" energy levels of electrons in metals overlap the energy level of the conduction band. Apply a voltage, and electrons in the overlap region will support current flow.
Do atoms of metallic elements tend to gain or lose electrons?
Metals usually lose electrons, this is why many charges are positive.
How many valence electrons do alkali metals lose to obtain an octet?
they lose one electron
How many electrons are in a cesium ion Cs plus?
Is metallic elements more likely to lose electron than nonmetallic elements?
Yes. Metals always lose electrons and non-metals gain electrons.
How many valence electrons do metals have?
Metals as found in the Periodic Table have no "extra" electrons. They are electrically neutral because they have the same amounts of protons and electrons or + and - charges respectively. However metals react with non-metals to form Ions, cations to be more precise, in this case they actually lose electrons resulting in a positive charge. In other words, metals never have "extra" electrons, they either have a neutral charge or they are lacking electrons and have a negative charge.
What type of element tends to lose electrons when bonds form?
Metals because metals are mostly on the left side of the Periodic Table and have fewer electrons.
How many electrons is the alkali metal losing when it becomes an ion?
Alkali metals lose one electron when it becomes an ion.
How many valence electrons are in aluminum?
Alkaline earth metals are group 2 elements and have 2 valence electrons.
How many electrons do group 1 elements lose to become ions?
Group 1 elements a.k.a. Alkali metals lose 1 electron to form 1+ ions
How many electrons does a nonmetal and metal receive during a chemical reaction?
In general chemical reactions, metals tend to loose electrons and non-metals gain electrons. The no. of electrons loosed by metals is the same as the no. of electrons gained by the non-metals.
How many electrons does boron lose when forming a ion?
lose three electrons
What is a term used to describe an element with fewer than 4 electrons its outer shell?
represent a group of elements called metals. per novanet.
