Exploring the Periodic Table

What are the general properties of metals?

• Metals have low density and are non-malleable.

• Metals are good conductors of heat and electricity, malleable, ductile, lustrous, and have high density.

• Metals are always brittle and dull.

• Metals are poor conductors of heat and electricity.

Name three common metals found in the periodic table.

• iron, copper, aluminum

• platinum

• silver

• gold

What distinguishes nonmetals from metals?

• Metals have higher electronegativity than nonmetals.

• Nonmetals are good conductors of electricity.

• Nonmetals are characterized by poor conductivity, higher electronegativity, and electron gain, unlike metals which are good conductors, have lower electronegativity, and lose electrons.

• Nonmetals lose electrons easily.

List two properties of nonmetals.

• Good conductivity of heat and electricity

• High malleability in solid form

• 1. Poor conductivity of heat and electricity; 2. Brittle in solid form.

• Ductile in solid form

What are metalloids and where are they located on the periodic table?

• Metalloids are identical to metals and located in the far left.

• Metalloids are only found in the d-block of the periodic table.

• Metalloids are gases that are found in the upper right corner of the periodic table.

• Metalloids are elements with properties between metals and nonmetals, located along the zig-zag line on the periodic table.

Give an example of a metalloid and its uses.

• Copper, used in electrical wiring.

• Iron, used in construction.

• Gold, used in jewelry.

• Silicon, used in semiconductors and integrated circuits.

How do metals typically react with nonmetals?

• Metals do not react with nonmetals at all.

• Metals react with nonmetals by transferring electrons to form ionic bonds.

• Metals react with nonmetals by sharing electrons to form covalent bonds.

• Metals react with nonmetals by absorbing electrons to form metallic bonds.

What is the significance of the 'stair-step' line on the periodic table?

• It shows the atomic number of elements.

• It indicates the reactivity of elements.

• It distinguishes metals from nonmetals and indicates metalloids.

• It represents the phases of matter at room temperature.

Which group of elements is known for being highly reactive metals?

• Alkali metals (Group 1)

• Lanthanides

• Transition metals

• Noble gases

What are some common uses of nonmetals in everyday life?

• Common uses of nonmetals include oxygen for breathing, nitrogen in fertilizers, carbon in organic compounds, sulfur in chemical production, and noble gases in lighting.

• Iron in construction materials

• Copper in electrical wiring

• Aluminum in packaging
