Here are the correct answers to fill in the blanks on your worksheet, broken down by section.
Metals, Nonmetals and Metalloids
The three major groups on the Periodic Table are the
metals,
nonmetals and
metalloids. Elements within each group have similar
physical and chemical properties.
Some of the physical properties used to distinguish between the three groups are:
*
Luster = the ability of a substance to reflect light. Usually the descriptive words are either
shiny or dull.
*
Conductivity = the ability of the substance to conduct
electricity or heat. This may be tested with a conductivity meter.
*
Malleability = the ability of the substance to be
hammered into sheets without breaking.
*
Ductility = the ability of the substance to be pulled into a
wire.
Metals are –
* found to the
left of the zigzag line on the periodic table.
*
solids at room temperature, except for
mercury, which is a liquid.
*
good conductors of electricity and
heat. But some are better conductors than others!
* metallic looking with a
luster (or shine).
*
ductile and can be drawn into wire, but some metals are more ductile than others.
*
malleable and can be hammered into sheets without breaking.
