Periodic
Table
of the
ElementsPeriodic: Having or marked by repeating
patternsTable: An arrangement of words, numbers, or symbols, or combinations of them, as in parallel columns, to exhibit a set of facts or relations in a definite, compact, and comprehensive form
Elements: A substance that cannot be broke down into simpler substances by chemical means
Metals: 87 of the 118 elements are metals. They appear on the left side of the Periodic Table.
Some common properties of metals are: Solid at room temperature
(except mercury which is a liquid) Good conductor of heat and electricity Lustrous on fresh surfaces Malleable and ductile
Metals
Nonmetals: Appear on the right side of the Periodic Table. 18 elements are nonmetals.
Eleven are gases at room temperature (H, N, O, F, Ne, etc.)
Five are solids (C, P, S, Se, I) One is a liquid (Br). Nonmetals are poor conductors of heat
and electricity.
Non-Metals
Metalloids: Seven elements are metalloids. Their properties are between those of metals and nonmetals. Metalloids are semiconductors and are important to
the electronics industry.
Metalloids
The Modern Periodic TableMendeleev
Set up the periodic table based on atomic mass Moseley
Set it up by atomic number rather than atomic massPeriodic Law – properties occur in a repeating
pattern when set up by atomic number.
