The document discusses the properties of metals. Metals are elements that are found in groups 1-2 and some in groups 13-15 on the periodic table. Key properties of metals include luster, ductility, malleability, and conductivity - metals are shiny, can be drawn into wires, hammered into thin sheets, and conduct heat and electricity well. The document also discusses different groups of metals, including alkali metals, alkaline earth metals, and transition metals, and how their properties and reactivity can differ based on their position in the periodic table.

2. Looking at the photo
do you think metal
conducts electricity?
Lightning is a form of
electricity and it seems
to follow through the
metal rod.

3. What is a metal?
• More than three-quarters of the
elements on the periodic table are
metals.
• With the exception of hydrogen, all of
the elements in groups 1-12 on the
periodic table are metals.
• Some of the elements in groups 13-15
are metals.

5. What is a metal? (cont.)
To be a metal, an element must have
certain properties.
