What are the physical properties of metals?

• Colorful, average conductors of heat and electricity, rigid, average melting and boiling points

• Dull, good insulators of heat and electricity, flexible, low melting and boiling points

• Transparent, poor conductors of heat and electricity, brittle, low melting and boiling points

• Luster, good conductors of heat and electricity, malleable and ductile, high melting and boiling points

What are some examples of physical properties of metals?

• Color, solubility, reactivity

• Luster, conductivity, malleability, and ductility

• Density, odor, taste

• Transparency, brittleness, volatility

How would you classify Indium?

• Metalloid

• Metal

• non-metal

• A gas

Where are metalloids located in the periodic table?

• At the top of the periodic table

• In the middle of the nonmetals

• Between metals and nonmetals

• At the bottom of the periodic table

Who arranged the known elements into horizontal rows of increasing atomic mass leaving gaps for as yet undiscovered elements?

• Mendeleev

• Meyer

• Newlands

• Moseley

Who suggested that the physical and chemical properties were related to the atomic number, rather than atomic mass?

• Meyer

• Mendeleev

• Moseley

• Newlands

The name of the elements in groups 3-12 (middle section) of the periodic table is the...

• Halogens

• Alkali Metals

• Transition Metals

• Solid Metals

What is the name of Group 2A?

• Alkali metals
• Alkaline-earth metals
• Transition metals
• Halogens

Which element would have the largest atomic radius?

• Nitrogen (N)

• Oxygen (O)

• Phosphorus (P)

• Sulfur (S)

The Periodic Table of the Elements is useful for revealing patterns and trends in the elements. Which statement accurately describes a pattern in the size of atomic radii in the Periodic Table of the Elements?

• Atomic radii decrease from left to right across a period and decrease from top to bottom in a group.
• Atomic radii increase from left to right across a period and increase from top to bottom in a group.
• Atomic radii decrease from left to right across a period and increase from top to bottom in a group.
• Atomic radii increase from left to right across a period and decrease from top to bottom in a group.
