chemical reactions 4. Compounds are formed when atoms of more than one element combine; a given compound always has the same relative number and kind of atoms. Atoms are the basic building blocks of matter; they are the smallest units of an element: An element is composed of only one kind of atom In compounds the atoms of two or more elements combine in definite arrangements Mixtures do not involve the specific interactions between elements found in compounds, and the elements which comprise the mixture can be of varying ratios. Atoms, Molecules and Ions Contd
All matter is made of atoms and atoms are indivisible, cannot be subdivided, created or destroyed
All matter is made of atoms and atoms are indivisible, cannot be subdivided, created or destroyed. Dalton's Atomic Postulate 2. All atoms of the same elements are identical in mass and properties (the same). if 2 or more different compounds are composed of the same 2 elements, then the ratio of the masses of the second element combined with a certain mass of the first element is always a ration of small whole numbers. carbon and oxygen form carbon dioxide and carbon monoxide; the ratio of carbon to oxygen between dioxide to monoxide is always 2:1). number of protons of each atom of that element.

We will consider the atom to be a spherical species, with a nucleus in the centre. Atoms consist mainly of three types of particles: Protons and Neutrons (which are found in the nucleus) and Electrons (which move around the atom outside of the nucleus).
Do elements, mixtures and compounds consist of atoms or molecules ?. .Atoms and molecules are usually the first chemical units to be introduced in school chemistry lessons
Do elements, mixtures and compounds consist of atoms or molecules ? Answer in words: Elements can consist of either atoms or molecules but if molecules then those molecules are formed only from atoms of the same type (that is, atoms of the same element). metals, consist of many atoms of the element packed very densely together, . copper, whose symbol is 'Cu'. Only a few elements exist naturally as a liquid at standard temperature and pressure. Atoms and molecules are usually the first chemical units to be introduced in school chemistry lessons. Ions are also important but are slightly more complicated so are usually introduced later.
