THE PERIODIC TABLE
![Page 2: T HE P ERIODIC T ABLE Groups are the vertical columns in the periodic table. The group number is located above each column. Periods are the horizonta.](https://reader038.fdocuments.us/reader038/viewer/2022110403/56649e835503460f94b84c42/html5/thumbnails/2.jpg)
Groups are the vertical columns in
the periodic table. The
group number is
located above each
column.
Periods are the horizontal rows. The number is located on the left of each row.
Groups are the most common way of classifying elements, but there are some regions of the periodic table where the
horizontal trends and similarities in properties are more significant than vertical
group trends

METALSGood conductors of heat and electrical conductors MalleableShinyHave lusterDuctileMostly solids at room temperature
Metals are located on the left side and the middle of the periodic table.

NONMETALS
Poor thermal conductorsPoor electrical conductorsBrittle SolidsLittle or no metallic luster
The nonmetals are located on the upper right side of the periodic table.
Nonmetals are separated from metals by a line that cuts diagonally through the periodic table.

LANTHANIDES
Silvery metals that tarnish easily Relatively soft metals, with high melting and
boiling points React to form many different compounds
Lanthanides are in the top row of the 2 rows located underneath the main body of the periodic table.

ACTINIDESRadioactive with positively charged ionsCombine directly with most nonmetals React with boiling water or dilute acid to release hydrogen gasTarnish readily in air
Actinides are in the row below the Lanthanides.

NOBLE GASESFairly nonreactive because they have little tendency to gain or lose electronsComplete valence shellHigh ionizatoin energies Very low electronegativitiesLow boiling points, all gases at room temperature
Noble gases are located in Group 18, on the far right of the periodic table
