A element is a unique substance that is composed of atoms having the same atomic number. Energy is the ability to do work.
it protons is the answer.
No. (Element is the word you're looking for.)
You think probable to diatomic molecules of hydrogen, oxygen, nitrogen and halogens.
a number having no physical meaning.
No. Elements are composed of atoms that have the same number of protons (atomic number) in their atomic nuclei. Compounds are composed of two or more elements that are chemically combined.

Anisole is a compound, not an element and so it does not have an atomic number. It is composed of carbon, hydrogen, and oxygen which have the atomic numbers 6,1, and 8 respectively.
Ammonia does not have an atomic number, as it is a molecular compound composed of nitrogen and hydrogen atoms. The atomic number refers to the number of protons in an atom's nucleus, and since ammonia is a compound, it does not have a single atomic number.
Probably sulfur, not sulphate. The atomic number of sulfur is 16.
Rust is primarily composed of iron oxide, which has the chemical formula Fe2O3. Since iron (Fe) has an atomic number of 26 and oxygen (O) has an atomic number of 8, the atomic number for rust would be 26.
Phosphate is a polyatomic ion, not an element and so it does not have an atomic number. It is composed of oxygen and phosphorus which have the atomic numbers 8 and 15 respectively.
