Many other elements, such. as most other nonmetals (O2, N2, S8, P4, etc.) occur as molecules. 2.6 Compounds contain atoms from two or more elements, thus the smallest unit must contain at least a pair of atoms. 2.7 Mixtures have variable composition; therefore, the amounts may vary. Compounds, as pure substances, have. constant composition, thus their composition cannot vary.
Variation in the number of electrons or neutrons does not change the type of element. Changing number of electrons produces ions while changing the number of neutrons produces isotopes. The modern periodic table is organized in order of increasing atomic number. The element's atomic mass in atomic mass units. This number is a weighted average mass of the element's isotopes. Mendeleev's original periodic table organized elements in order of increasing atomic mass or weight.
