Are electrons in non-polar covalent molecules localised or delocalised amd mobile?

Either one is possible. In benzene, the twelve electrons in the six carbon-hydrogen bonds are localized and the remainder of the electrons are delocalized and can move freely around the benzene ring.

How are metalic bonds different from ionic and covalent bonds?
The difference is that metallic bonds have the electrons fully delocalised, spread throughout the metal lattice and they are free to move. In ionic bonds the electrons are all localised onto the anions and cations. In covalent bonds, generally the electrons are shared and generally not delocalised although there are exceptions of course graphite is a reasonable conductor of electricity
How is the position of electrons involved in metallic bonding different from the position of electrons that form ionic and covalent bonds?
the electrons involved in metallic bonding are delocalised - they are free to move which accounts for electrical conductivity. In ionic bonds the electrons are tightly bound to individual atoms. Generally covalent bonds have localised electrons, in pairs in individual bonds. However there are delocalised electrons in some situations - take graphite extensive pi bonds allow for delocalisation and electrical conductivity.
What is the arrangement of electrons in a covalent bond?
usulally they are shared and are localised around the 2 atoms being bonded. In 3 center 2 electron bonds as in B2H6 they are across 3 atoms. Also there are delocalised covalent bonds , delocalised across more than two atoms- examples graphite, benzene.
Is graphite a molecular or ionic compound?
Graphite is a giant molecule bonded with covalent bonds.Some of the bonds involve delocalised electrons.
Do covalent networks conduct electricity?
No generally. Graphite with delocalised electrons does. Silicon is a semiconductor, it has a slight conductivity which increases with temperature

What is a covalent electron?
In covalent chemical bonds sometimes the electrons are loosely called "covalent electrons" as they are localised.
How is ionic bonding differant to covalent bonding?
In ionic bonding electrons are transferred from one element to another and are localised and not shared. the force of attraction in ionic bonding is electrostatic. In covalent bonding electrons are shared, or in some cases delocalised as in benzene. The source of the strength of a covalent bond is a quantum effect.

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.
What is it called when electrons are shared in bonds?
A covalent bond is when electrons are shared in bonds.

What do nonpolar covalent molecules share?
Nonpolar Covalent Bonds share electrons
Is dichlorobenzene a ionic or covalent bond?
Benzene is a covalent compound. It is formed of 6 Carbon atoms and 6 Hydrogen atoms which all share electrons in covalent bonds. A ring of delocalised electrons sit above and below the plane of the carbon atoms making Benzene stable and relatively unreactive.
Why does carbon not conduct electricity?
To conduct electricity a substance needs charged particles free to move. Metals have metallic bonding, so they have delocalised electrons free to move. Graphite, a covalent network compound, also has delocalised electrons. Ionic compounds conduct when molten or in solution because the ions break free from the crystal lattice and can move. Since carbon dioxide is covalent molecular bonding, it has neither delocalised electrons or ions, and this lack of charged particles free to move means it does not conduct.
