No. Chemical compounds contain two or more different elements. H2O is a compound that does not contain a metal.There are many other examples, all the organic compounds for instance.
It must be 400, because the compound must contain at least one sulphur atom with atomic mass 32.
A single atom of any element can not be a molecule in the strictest sense, because a molecule must contain at least one chemical bond. (This does not mean that a single atom of gas can not be a kinetic-molecular theory unit, as is true for the noble gases.) A single atom of any element also can not be a compound because that by definition must contain at least two distinct elements.
Ma ????? you must mean, since that is the correct atom to atom charge count, Na2CO3 Sodium carbonate
By definition, ethers must contain at least one oxygen atom.
The Group 1 compound must be heated more because, force the carbon dioxide to break off and leave the metal oxide.
It must be 400, because the compound must contain at least one sulphur atom with atomic mass 32.

A compound must have at least two atoms of different elements.
Oxyacid contains hydrogen, oxygen (at least one O atom must be bound to hydrogen), 1-2 other elements; oxyacids release ions.

At least one.
Calcium Chloride is an ionic compound. You see, for a substance to be classified as either a non-metal or a metal, it has to be in elemental form. Calcium Chloride is a compound, so you can't say whether it is a non-metal or a metal. However, of the elements that make up this compound, Calcium is a metal and Chlorine is a non-metal.
Atoms are made up of at least one proton, at least one nuetron, and at least one electron. The number of electrons an atom has must be equal to its protons, otherwise, it is called an ion.
No. Sulfide is simply a sulfur atom with a negative charge. To be organic a compound must contain carbon.
Part of the definition of a compound is that it must contain atoms of at least two distinct elements.
By definition, ethers must contain at least one oxygen atom.
