Periodic Table Review

In the modern periodic table elements are arranged by:

• atomic mass
• atomic number
• valence electrons
• number of isotopes

Each horizontal row in the periodic table is called a 

• group
• period
• cluster
• unit

Each vertical column in the periodic table shares similar properties and is called a 

• period
• group or family
• cluster
• unit

The atomic number tells you what?

• number of electrons
• number of protons
• number of neutrons
• both electrons and protons in an atom.

A negatively charged particle that moves around the nucleus is a(n)

• proton
• neutron
• electron
• quark

The atomic number of this pictured element is

• 28
• 58.6934
• Ni
• Nickel

Which elements are good conductors of electricity?

• metalloids
• metals
• non-metals
• meteors

Which group of elements has properties of both metals and non-metals?

• metalloids
• metals
• non-metals
• gases

Most of the elements in the periodic table are

• metalloids
• metals
• non-metals
• gases

What is the mass number?

• the number of protons
• the sum of the number of protons and the number of neutrons in the nucleus of an atom
