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.
An element is distinguished by always having the same number of protons in the nucleus. Next > However, there can be a variable number of neutrons. 54 Isotopes and Atomic Mass This will affect the average mass of an atom of an element. If we take a specific example it will become clear. An isotope of an element has the same atomic number but has a different number of neutrons. The isotope of an element can be indicated in two ways: Next > How to write it Atomic number (may not be present) Fe Atomic mass 26 Using the elements symbol (numbers can either be to the left or the right of the symbol): Using the elements name: Iron- 54 Fe54 26 Iron, atomic number 26, has four naturally occurring isotopes. Next > Example They are:
