Properties of Selected Elements

• Malleable - can be hammered into shapes

• Has a shiny appearance (luster)

• Conducts heat (has high thermal conductivity)

• Conducts electricity (has high electrical conductivity)

​

Properties or characteristics of Metals

• The dark zig-zag line on the Periodic Table separates the metals from the nonmetals.

• Most of the elements on the Periodic Table are metals and are found to the left of the zig-zag line.

• Group 1 Metals are called ALKALI METALS.

​

Location of Metals

• Brittle (brittleness) - breaks easily

• Lacks luster (Dull, no shine)

• Does NOT Conducts heat (has low thermal conductivity)

• Does NOT conducts electricity (has low electrical conductivity)

​

Properties or Characteristics of Nonmetals

Nonmetals are found to the right of the zig-zag line on the periodic table.

Hydrogen is also a nonmetal but it is found in group 1

​

Location of Nonmetals

Elements bordering the zig-zag line, are called metalloids, and have properties of both metals and nonmetals.

The MUSt touch the Zig-Zag Line to be called metalloids.
Aluminum is the exception

​

Metalloids

They sit on the staicase and under the staicase
