False. A molecule is the smallest part of a compound that can still be indentified as a compound as it may contain several atoms of different elements. A single atom can only identify a single element, not a compound which it may have been a part of.
The number of elements in a compound can be determined by looking at the chemical formula and identifying each element's symbol. For example, the compound CO2 has two elements, carbon and oxygen. Another example, glucose, has the formula C6H12O6, and has three elements, carbon, hydrogen, and oxygen.
Add the compound to nitric acid untill the solution is near colourless, then following this add 2-3 drops of silver nitrate, if a white precipitate forms then the chloride ion is present. to identify if the Cation is lead, try doing a flame test with an emission spectra. cl- + ag+ ---> AgCl
It is a compound.
Compare the infra-red spectra of propan-1-ol and propan-2-ol. Both compounds contain exactly the same bonds. Both compounds have very similar troughs in the area around 3000 cm-1 - but compare them in the fingerprint region between 1500 and 500 cm-1. The pattern in the fingerprint region is completely different and could therefore be used to identify the compound. So . . . to positively identify an unknown compound, use its infra-red spectrum to identify what sort of compound it is by looking for specific bond absorptions. That might tell you, for example, that you had an alcohol because it contained an -OH group. You would then compare the fingerprint region of its infra-red spectrum with known spectra measured under exactly the same conditions to find out which alcohol (or whatever) you had.

No, it is not.

This is a compound sentence, and it smells bad.
Each compound has a specific absorption spectra.
It is a compound of tin and fluorine (if it has two parts to its name or ends in -ide, it is not an element).

I do not believe that any chemist would choose to identify a compound by using only the melting point; why create such difficulties for yourself?
it is a mixture, specifically homogenous because you cannot identify the particles of it......
