Most of the elements in the periodic table can be described as:

• Nonmetals

• Metals

• Metalloids

• Noble Gases

A way of organizing the elements based on their chemical properties is the:

• Alphabetical table
• Random table
• Periodic table
• Numerical table

A period’s number on the periodic table corresponds to the number of:

• electrons in the outermost shell
• energy levels or shells
• neutrons in the nucleus
• protons in the nucleus

 Horizontal rows on the periodic table are called:

• periods
• blocks
• columns
• squares

Characteristics of non-metals include all of the following EXCEPT:  

• ductile

• poor conductors

• dull

• brittle

• bottom side
• left side

An atomic mass unit is the approximate mass of a single:

• proton or neutron
• electron or photon
• molecule or compound
• cell or tissue

An example of a metalloid, elements with properties between metals and non-metals, is

• Boron
• Gold
• Oxygen
• Carbon
