Within matter, atoms and their constituents are constantly in motion.

The arrangement and motion of atoms vary in characteristic ways, depending on the substance and its current state (e.g., solid, liquid).

Atoms also combine due to these forces to form extended structures, such as crystals or metals.

The varied properties (e.g., hardness, conductivity) of the materials one encounters, both natural and manufactured, can be understood in terms of the atomic and molecular constituents present and the forces within and between them.

Despite the immense variation and number of substances, there are only some 100 different stable elements.



Moreover, the table’s patterns are now recognized as related to the atom’s outermost electron patterns, which play an important role in explaining chemical reactivity and bond formation, and the periodic table continues to be a useful way to organize this information.

And one thing that should be worrisome for straight men is the size of their disadvantage in the market.
