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.
