Why amonia solution of alkali metals are blue in clour?
Solvated electrons. The electrons "dissolve" from the metal. It's blue because electrons have a different absorption spectra.
Is metal an atom a molecule or a compound?
A metal is normally viewed as cations in a sea of delocalised electrons. It is the metal atoms which donate their valence electrons to the sea of delocalised electrons.
What metal has 30 electrons?
Zinc has 30 electrons.
Alkali metals cannot be used in voltaic cells?
Lithium is an alkali metal and is used in the highest energy capacity cells made.
When metal corrodes the metal atoms lose what?
electrons

Why does silver conduct electricity?
Because it's a metal. No, seriously, that's why. Metal atoms share electrons in what's called the "metallic bond"... electrons are not strongly associated with one or even a few atoms, but can fairly freely move throughout the entire bulk of the metal. These "conduction band" electrons make it easy to put electrons in at one end and get (different) electrons out the other end of a piece of metal.
How is covalent bond different from an ironic bond?
A covalent bond is a bond between a non-metal and another non-metal, and shares electrons, while an ionic bond is a bond between a non-metal and a metal and, instead of sharing electrons, they form ions.
What metal and has 28 electrons?
nickel has 28 electrons and is in the metal family
What is the sea of electrons and what purpose gives metal?
the actom is made up of nucleus with negative electrons revovling around it.Molecules may consist of like atoms, as in oxygen,or of unlike atoms ,as in cabon dioxide. Different Molecules form different matters. the sea of electrons in metal are able to conduct electricity.
What are the free electrons in a metal called?
Free electrons in a metal are called delocalized.
Is metal an atom a molecule or a compound?
A metal is normally viewed as cations in a sea of delocalised electrons. It is the metal atoms which donate their valence electrons to the sea of delocalised electrons.
The electric current in a metal conductor is carried by?
Valence shell electrons. A metal is formed from a lattice of positive ions in a sea of delocalized electrons. These electrons are the valence shell electrons of the metal atoms and they are the ones that carry the charge during conduction.
Do nonmetal donate or accept electrons?
If a non-metal combines with a metal, then the metal will donate electrons and the non-metal will accept electrons. An ionic bond is the result to form an ionic compound. If the non-metal combines with another non-metal, then both will share the electrons resulting in the formation of a covalent bond between them. The molecule is known as covalent compound.
What metal has 30 electrons?
Zinc has 30 electrons.
What are free electrons of conductor?
First we have to define the word an electron, An electron is negatively charged particle. A metal is a substance consists of number of both electrons and protons. Electrons emitted from the metal surface through different ways such ways as Thermionic, Photoelectric, etc. Free electrons of conductor are electrons emitted from conductor when it disturbed through ways as mentioned above
Alkali metals cannot be used in voltaic cells?
Lithium is an alkali metal and is used in the highest energy capacity cells made.
