Two reasons: # Smaller than a single atom of an element, it ceases to be an element. # The energies available to chemical means is a million times too small to break apart an atom of an element (the nucleus) to "smaller parts".
It means that elements can be separated by their chemical simulatries as they are on the periodic table of elements.
A compound can only be separated into elements by chemical means.
Each structure is composed of elements. Each of these elements, in its turn, can be subdivided on some more smaller elements. So this what substructure means.
Compound is a substance that consists of two or more elements which are chemically bonded. They can only be separated by using chemicals or other means. however mixture can be separated by physical means.
Yes it can. Water, table salt, and sugar are all examples of compounds and can all be decomposed into simpler substances through physical means.^^ I believed that water and table salt would be a mixture, mixtures are the non-chemical means not compounds, with compounds there is a chemical change.

Elements
A compound can only be separated into elements by chemical means.
That means that it can be separated into smaller factors.
Various chemical compounds eg Hydrogen Peroxide.
The elements of a chemical compound can be separated only by chemical means, but not by physical means.
Matter is a pure substance if it can only be separated by chemical means, NOT physical means. This could be a compound or an element. The opposite is a mixture which can be separated/broken into smaller parts by physical means.

chemical compounds can be separated into their component elements by physical means like sifting or filtering
The components of a mixture can be separated by physical means, such as filtration or distillation. The components of a compound can be separated only by chemical means, meaning a chemical reaction.
elements have unique sets of properties
