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 kind of substance contains a sea of electrons?
Metals (such as aluminum) are held together by "metallic bonding" which can often be described as a "sea of electrons"
Does metallic bonding involve free-floating electrons?
Yes that is how metallic bonding is modeled - a sea of electrons.
How do the electron's in a metallic bond affect the metal?
Because of the common sea of electrons, these electrons can move readily, creating electricity.
How far up in the sky are satellites?
There are currently 32 GPS satellites Orbiting earth at 20,000Kms above sea level There are also 24 GLONASS satellites (The russian version of a GPS satellite) Which many high end GPS receivers will use in conjunction with the standard GPS satellites. These orbit a little lower than GPS at arond 19,000Kms above sea level. There are 4 Galileo Satellites, which are currently un used, but are the start of the European satellite constealltion which is a work in progress. They orbit at 24,000Kms above sea level. On top of all that, there are 10 Chinese navigation satellites called COMPASS orbiting in an orbit above China and Asia. They orbit at around 21,000 Kms above sea level.
What happens to electrons after a chemical bond is formed?
If the starting point are elements then the inner shell electrons (non valence) these orbit the nuclei of the atoms and the formation of a chemical bond does not affect these materially. What happens to the valence electrons depends on the bond formed. In an ionic bond electrons are transferred from say the metal atom to the nonmetal- these electrons essentially "orbit" the nuclei of the cations and anions. They are "localised". When a covalent bond is formed the valence electrons involved are shared between the atoms, they "orbit" both nuclei. When the bond is polar covalent they spend a little more time nearer the more electronegative element. When a "delocalised"covalent bond is formed as in bezene or graphite the electrons orbit a number of atomic nuclei. In a metallic bond the valence electrons are also delocalised (the sea of electrons model) across the metal lattice, but in transition metals there is additional bonding between electrons in d orbitals (the tight bound electrons) and these electrons are essentially localised.
Where can you find a sea urchins?
Sea urchins are found generally in the sea, however they can also be found in/on rock pools or areas near to the sea.
What does the phrase sea of electrons mean?
A sea of electrons can be found in metals. The positive ions are arranged in fixed positions, while the electrons 'float' or 'wander' among the the positive ions. This makes metals good conductors of electricity. ----------------- Electrons of metals flow freely
What bond has the characteristic of a sea of mobile electrons?
Metallic bonds have the characteristics of a sea of mobile electrons.
Where is oil found in India?
Oil is found in Rajasthan, Gujarat and Assam. It is also found near Mumbai, in the sea. The place in the sea where oil is found is known as 'Bombay High'.
Where can Phrosphurus be found in the world?
Phosphorous may be found in the sea, and in bones. As a consequence of it being in the sea, it my also be found in some limestone deposits, and in seabird guano.
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.
Why are metals good conductors of electrcity while rubber and plastic are insulators?
the reason metals are good conductors is because in their subatomic structure electrons float as if in a sea, also called a sea of electrons that is why you can magnetize most metals and they conduct electricity.
What kind of substance contains a sea of electrons?
Metals (such as aluminum) are held together by "metallic bonding" which can often be described as a "sea of electrons"
Which types of atoms pool their valence electrons to form a sea of electrons?
Metals
Where do most sea turtles live?
Sea turtles are found in almost every ocean exept for Canadian places. They are also found in warm seas.
What does the term sea of electrons in relation to the electrons in metallic bond?
In metals electrons are delocalized and in a permanent movement, as a gas.
