Detailed explanation-1: -Elements are those substances that are composed of one kind of atom. They cannot be broken down into simpler types of matter by either physical or chemical means. They can exist as atoms (for eg: Neon) or molecules (for eg: Nitrogen).
Detailed explanation-2: -An element is a substance that consists of atoms which have the same number of protons, that is, the same atomic number. They are chemically the simplest substances and hence cannot be broken down using chemical methods. For example, hydrogen and oxygen.
Detailed explanation-3: -Compounds are the chemical substances which can be further subdivided into simpler substances through chemical methods only. This is due to the fact that compounds are made up of chemical combination of elements, thus they can be separated by only chemical means.
Detailed explanation-4: -Element can not be broken down chemically. Elements are made of atoms of only one kind and that cannot be separated by ordinary chemical means into simpler substances.
