1.3 Elements

All known elements are organized into a chart known as the

• element table

• group table

• periodic table

• metal-nonmetal table

The vertical columns of the periodic table are called

• periods

• rows

• groups

• chemicals

A period is

• a horizontal row of elements in the periodic table.

• a vertical column of elements in the periodic table.

• a region of two or more columns in the periodic table

• another name for the for the periodic table

Which of the following is not a property of metals?

• malleability

• good electrical conductivity

• brittleness

• good heat conductivity

Metalloids lie between metals and nonmetals on the periodic table. They tend to be

• nonconductors

• conductors

• semiconductors

• unreactive

The “shininess” of a metal is called its

• luster

• color

• streak

• malleability

The element carbon is classified as a

• metal

• nonmetal

• metalloid

• noble gas

Which of the following is not true of nonmetals?

• Many are gases.

• Many are ductile.

• As solids, they tend to be brittle.

• Most are poor heat and electrical conductors.

Which of the following elements is a metalloid?

• neon

• selenium

• mercury

• silicon

Which of these describes noble gases?

• massless

• unreactive

• good heat conductors

• good electrical conductors
