Juguemos to why?
Why metals shine? ... And then some.
To answer this question is well to remember a note of Science Easy on the tour of the periodic table.
metals themselves are the Group IA (alkali) and IIA (alkaline) of the periodic table, but in everyday life metal properties to assign all that glitters, it conducts electricity and heat and can work on by-wire (ductile) or plate (malleable). Their atoms are characterized by electrons in the top level with high tendency to move to other items in need (not metal) so that these negative electric charges can be lost thus remaining fairly easily with electrical properties similar to those gases which precede them in the periodic table, stability models of nature.
Most elements react chemically joining each other, with the goal "almost smart" to be in the same power of these noble elements.
When speaking in chemistry from the metal union say:
. "Positive nuclei immersed in a sea of \u200b\u200belectrons" This is the metaphorical description of the model gives cash Science! Hence, this sea-mail has the ability to move through the core and does not belong any of them. BY HIGH MOBILITY ELECTRONICS ESA is that
metals are substances that easily lead
v electricity, heat
v v possess a characteristic brightness are
v v are malleable ductile
Such physical properties are related with the atomic structure, as the positive nuclei occupy fixed locations in space, respecting a rigid geometry (lattice) but the electrons move freely around them, without belonging to any in particular that is how the mobile tag gives the substance great power electric driving, do not forget that electricity is electrons in movimiento.Su brightness also has to do with the mobility of charges as the incidence of light increases the motion of surface electrons as they reflect from all angles to be heat conduction observe.La also make these small electrical particles carrying the heat energy from one point to another metal.La metal structure is stabilized by the attraction of the nucleus with its sea-mail, but as in the sea there is no electron in preference to a particular nucleus, this gives malleability and ductility substance so they are easy to mold and are able to produce sheets or wire used by man permanently in all industrias.Con regarding its structure can not talk about molecules and the positive nuclei (cations) bind all to integrate a huge single aggregate (macromolecule) supported by the electron cloud that structure neutraliza.La crystalline metal is what gives it greater or lesser hardness and also making changes to their physical characteristics such as melting point (passage from solid to liquid) and boiling (liquid to gas passage.)
