Metals conduct electricity because they have delocalised electrons. These carry electrical charge through the metal. Many pure metals are too soft for many uses. They can be made harder by adding ...

You might think Earth is a big lump of rock, hard on the outsideand soft in the middle—but quite a lot of it is actually metal. Whatexactly is metal? Over three quarters of the chemical elementsthat occur naturally on our planet are metals, so it's almost easierto say what metal isn't. Chart: Roughly half of Earth's crust is made from metallic or s...
Whether you're assembling airplanes or buildingbatteries, youneed metals—and lots of them. The snag is that metals generallydon't occur in the ground in exactly the way that we'd like to findthem, in their pure form and in deposits large enough to make itworth our while to extract them. Often they're buried in rock withdeposits of other metals and ...

With so many chemical elements classified as metals, you mightthink it would be difficult to generalize about them. But thatproblem is true of pretty much any generalization: every house isdifferent, but we can still say that houses tend to have doors,walls, windows, and a roof and provide shelter from the weather—andwe can all sketch one on paper. The generalizations we make about metals are: 1. They are mostly solid (at everyday temperatures), crystalline (their atoms are stacked up in orde...

Metals are usually crystalline solids. In most cases, they have a relatively simple crystal structure distinguished by a close packing of atoms and a high degree of symmetry . A metal's valence electrons —that is, the outermost electrons around an atom, which can be shared with other atoms—are non-localized, or free, and they are the ones that conduct an electric current by moving between ...

Many metals, such as copper, iron and steel, are good electrical conductors. That is why the parts of electrical objects that need to let electricity pass through are always made of metal.
Aug 30, 2024 · The electrical conductivity of metals is a result of the movement of electrically charged particles. The atoms of metal elements are characterized by the presence of valence electrons, which are electrons in the outer shell of an atom that are free to move about. It is these "free electrons" that allow metals to conduct an electric current.
This is referred to as a 'sea of electrons'. Given that these electrons are delocalised and are able to carry charge through the metal lattice, this explains why metals can conduct electricity. To answer this question we need to think about the bonding that occurs within metals. Metallic elements form strong lattices due to the metallic bonding.
