Exploring Metals and Nonmetals

What is a metal?

• An element that is typically a gas or brittle solid

• An element that is typically solid, shiny, malleable, and a good conductor of heat and electricity

• An element that has properties of both metals and nonmetals

• A pure substance composed of different types of atoms

Which of the following describes a nonmetal?

• Shiny and malleable

• Good conductor of heat and electricity

• Typically not shiny, not malleable, and poor conductors of heat and electricity

• Always a liquid at room temperature

What is malleability?

• The ability of a substance to transfer heat or electrical energy

• The ability of a material to be permanently reshaped without breaking or cracking

• The way the surface of a substance shines or reflects light

• The arrangement of elements in the periodic table

What is an element?

• A mixture of different substances

• A pure substance composed of the same type of atom throughout

• A compound made of two or more different atoms

• A solution of metals and nonmetals

Which of the following best describes metalloids?

• Elements that are always gases

• Elements that have properties of both metals and nonmetals

• Elements that are only found in compounds

• Elements that are always shiny and malleable

What does luster describe?

• The ability of a substance to conduct electricity

• The way the surface of a substance shines or reflects light

• The ability of a material to be reshaped

• The arrangement of atoms in a molecule

What is the Periodic Table of Elements?

• A chart that shows the phases of the moon

• A table in which all the known elements are arranged by properties and are represented by chemical symbols

• A list of all known compounds

• A diagram showing the structure of atoms

Which of the following is a property of metals?

• Poor conductivity

• Brittle and dull

• Malleable and shiny

• Always gaseous at room temperature

Which of the following is NOT a characteristic of nonmetals?
