These solutions may offer step-by-step problem-solving explanations or good writing examples that include modern styles of formatting and construction of bibliographies out of text citations and references. Students may use these solutions for personal skill-building and practice. Unethical use is strictly forbidden.A chemical element (simple substance, elementary substance) is a substance that consists of only one kind of atomic sort, it has all the atoms of the same atomic number of PTE. From all the substances available in nature, approximately 20 are available as chemical elements.
Those are N2, O2, H2, He, Ne, Ar, Kr, Xe, Rn, Hg, C, S, Cu, Ag, Au, and some platin metals. Difference - very small number of pure elements in nature.
When atoms bond in complex particles, they form molecules. A molecule can be made out of two or more atoms. If a molecule is made out of the same atoms, it is the molecule of an element, and if a molecule is made from different atoms it is a molecule of the compound.
The difference of a compound
When elements are mixed to produce a compound during a chemical reaction, elements lose their properties and the compound has different properties.
Also, different proportions give different compounds.
Eq. By mixing different amounts od C and O2, we may get two different molecules – compounds
On the other hand,elements always have the same properties....
