Mixtures are either homogeneous or heterogeneous . Pure substances are either elements or compounds .

Difference between pure substances and mixtures? A pure substance is an element or compound that is chemically mixed and can nit be split apart from each other.A mixture is two things physically put together that can be taken back apart.

Difference between elements and compounds?
compounds contain atoms that are chemically combined . A element contains the same kind of atom.

According to the modern version, the atoms of each element are effectively identical, but differ from those of other elements, and unite to form compounds in fixed proportions.


Parts:
  • Everything is composed of atoms, which are the indivisible building blocks of matter and cannot be destroyed.
  • All atoms of an element are identical.
  • The atoms of different elements vary in size and mass.

Atoms consist of electrons surrounding a nucleus that contains protons and neutrons. Neutrons are neutral, but protons and electrons are electrically charged. Protons have a relative charge of +1, while electrons have a relative charge of -1. The number of protons in an atom. is called its atomic number.
