Elements Microscopic view of the atoms of the element argon (gas phase). Microscopic view of the molecules of the element nitrogen (gas phase). Note that an element: consists of only one kind of atom, cannot be broken down into a simpler type of matter by either physical or chemical means, and can exist as either atoms (e.g. argon) or molecules (e.g., nitrogen). A molecule consists of two or more atoms of the same element, or different elements, that are chemically bound together. Note that the two nitrogen atoms which comprise a nitrogen molecule move as a unit. Compounds Microscopic view of the molecules of the compound water (gas phase). Oxygen atoms are red and hydrogen atoms are white.

Unformatted text preview: Note that a compound: • consists of atoms of two or more different elements bound together , • can be broken down into a simpler type of matter (elements) by chemical means (but not by physical means), • has properties that are different from its component elements, and • always contains the same ratio of its component atoms. Mixtures Microscopic view of a gaseous mixture containing two elements (argon and nitrogen) and a compound (water). Note that a mixture: • consists of two or more different elements and/or compounds physically intermingled, • can be separated into its components by physical means, and • often retains many of the properties of its components....
