What elements are in metallic bonding?
Although the term "metallic bond" is often used in contrast to the term "covalent bond", it is preferable to use the term metallic bonding, because this type of bonding is collective in nature and a single "metallic bond" does not exist. Not all metals exhibit metallic bonding: one such example is themercurous ion (Hg2+2), which forms covalent metal-metal bonds.However the vast majority of metals have a metallic bond.
What bond type is glycerine?
Covalent bonding and some of these bonds (C-O and O-H) are polar.
Why is methane insoluble but methanol is soluble?
Generally speaking 'like dissolves like' so when you thinking if a molecule can dissolve in a particular solvent, you need to decide what type of bonding that solvent can exhibit and what bonding the molecule in question exhibits. So for example water can exhibit hydrogen bonding. This means for something to be able soluble in water, it too needs to be able to exhibit hydrogen bonding. Methane only contains hydrogen and carbon and thus, will not exhibit hydrogen bonding. However, methanol has carbon, hydrogen and oxygen and therefore, can exhibit hydrogen bonding. As a result, using the 'like dissolve like' approach we can see why methane will be insoluble in water but methanol will be soluble.
Most substances that have molecules with approximately the same weight as water molecules are gases at room temperature. Water is a liquid at room temperature. Water is a liquid at room temperature be?
...because water molecules have strong intermolecular forces (hydrogen bonding) holding the moelcules together in the liquid state. Most other substances with similar molar mass do not exhibit hydrogen bonding, and thus they exist as gases.
What does not exhibit the property of adaptation?
Tonic receptors
Does metallic bonding occur between atoms of copper or chlorine?
Metallic bonding occurs between copper atoms. Only copper is a metal and has the characteristics needed for metallic bonding. Metallic bonding occurs between atoms with low electronegativities (low tendency to attract electrons from other atoms) and low ionisation energies (little energy required to remove electrons from the atoms). The low tendency for the metallic atoms to keep their electrons allow their electrons to be shared between the atoms, which thus become cations. The cations tend to be very closely-packed; they are not repulsed by their similar positive charges, but attracted to the electrons flowing freely between the cations. Metallic bonding therefore occurs between copper atoms, which have low electronegativity and ionisation energy. Chlorine atoms have some of the highest electronegativity and ionisation energy of all elements, and thus do not exhibit metallic bonding.

Are there any non metals?
No. Metal is a state of matter, not a chemical property. All elements are able to exhibit the metallic state at the right temperature and pressure. What we colloquially refer to as "metals" are those few elements that exhibit the metallic state at temperatures and pressures that are more common to us. But even hydrogen will become metallic at an estimated pressure of 25 GPa.
What compounds exhibit ionic bonding?
NaCl
Metallic solids do not exhibit what?
Variable melting points
Which molecule will not exhibit hydrogen bonding?
FON Remember this as it mean only hydrogen bonded to fluorine, oxygen and nitrogen will exhibit hydrogen bonding H2O ( water ) = hydrogen bonding as hydrogen is bonded to oxygen CO ( carbon monoxide ) = no hydrogen bonding Think electronegative differences.
What type of bonding are all diatomic exhibit?
covalent bonds
What bond type is glycerine?
Covalent bonding and some of these bonds (C-O and O-H) are polar.
Type of bonding water molecules exhibit?
Within the molecule itself, water exhibits ionic bonding. Between the water molecules, there is hydrogen bonding.

Would you expect SO3 to exhibit delocalized pi bonding?
yes
