Elements and the Periodic Table

Elements and the Periodic Table. Classification is arranging items into groups or categories according to some criteria. The act of classifying creates a pattern that helps you recognize and understand the behavior of fish, chemicals, or any matter in your surroundings. Classifying Matter.

Atomic Structure

Atomic Structure. Mass Number. Actual masses of atoms are frustrating to work with.Therefore we use relative comparisons of the masses of atoms. We use the atomic mass unit (amu) which is one-twelfth the mass of a carbon atom that contains six protons and six neutrons.

Chapter 3 - Stoichiometry Average Atomic Mass

Chapter 3 - Stoichiometry Average Atomic Mass. Many elements have a # of naturally occurring isotopes. Their atom percents in nature are known as their isotopic abundances. Isotopic abundances and isotopic masses can be measured using mass spectroscopy. When calculating average atomic mass:.

Review

Review. Isotopes. J.J. Thomson saw that there were two different neon atoms in the cathode ray tube These atoms were different in mass, but the same chemically Atoms of the same element that have a different mass are known as Isotopes. Isotopes. Contain the same number of protons
