What describes characteristics of a metallic bond?
Electrons move freely among many metal nuclei
What allow valence electrons in metals to move throughout the metal?
metal atoms being so close to one another that their outermost level overlap. Cause of the overlapping metallic bonds extend throughout the metal in all direction, so valence electrons can move throughout the metal.
Which direction do electrons move in when metals react with non metals?
During this type of reaction, the electrons would move from the metal to the non-metal. The transfer of electrons allows both material to maintain a full outer valence.
What will a non-metal do with its valence electrons?
Nonmetals attract electrons.
What happens to valence electrons as you move across the row?
The number of valence electrons increases.
Conductivity in a metal results from the metal atoms having?
highly mobile electrons in the valence shell
Why are the valance electrons of metallic bonds different from other bonds?
In a metal the valence electrons delocalize into the conduction band, becoming an "electron gas" that fills the metal's bulk volume.In covalent bonds the valence electrons are shared between local pairs of atoms.In ionic bonds the valence electrons leave the "metal" and move to the "nonmetal" creating a pair of separate oppositely charged ions.In resonance bonds the valence electrons oscillate between being shared between two nearby local pairs of atoms.etc.To summarize in metals the valence electrons become delocalized, in other bonds the valence electrons stay local.
What will a metal do with its valence electrons Why?
they are making metal bonds. that is the purpose.
How many valence electrons does an metal have?
1
What metal has two valence electrons?
calcium
How many valence electrons are in iridium?
2 valence electrons are in iridium because iridium is a transition metal. Most transitions metal would have 2 valence electrons because the group before the transition metals are the alkaline-earth metals which contains 2 valence electrons in that group making the transition metals have 2 valence electrons.
What are the electrons when metal atom and non metal atom react?
When a metal reacts with a non-metal, the electrons move from the metal to the non-metal. This is because the metal can achieve valence when it loses the electrons in its outer shell. The non-metal can also achieve full valence by gaining the electron in its outer shell.
