Reading the Periodic Table

How is the periodic table arranged?

• by atomic mass

• by atomic number

• by chemical symbol

• by element name

What is the atomic number?

• the number of protons

• the number of neutrons

• number of electrons

• the number of protons plus neutrons

What is the atomic mass?

• the number of protons

• the number of neutrons

• number of electrons

• the number of protons plus neutrons

How can we find the number of neutrons in an atom?

• add the atomic mass and the atomic number

• equal to the number of protons

• subtract the atomic number from the atomic mass

How can we find the number of electrons?

• add the atomic mass and the atomic number

• equal to the number of protons

• subtract the atomic number from the atomic mass

Where are the groups on the periodic table?

• columns

• rows

What do elements in the same group have in common?

• chemical properties

• number of protons

• physical properties

• energy levels

What do elements in the same period have in common?

• chemical properties

• number of protons

• physical properties

• energy levels

Where are the periods of the periodic table?

• columns

• rows

Where are the metals found on the periodic table?

• along the stairstep

• to the left of the stairstep
