similar _______ were grouped

together

• Protons

• Properties

• Valence Electrons

• Orbitals

Comparing Mendeleev's table with the current version of the Periodic Table

Multiple Select

Which two statements about 'periods' in the table are correct?

• Periods go across in rows and are in increasing atomic number (not atomic mass)

• As elements move across the period (right to left) the number of valence electrons (electrons in the outer shell) increases

• Elements in the same period have the same number of protons

• Periods are he vertical columns from top to bottom

Multiple Select

Which two statements about groups are correct?

• Groups go across in rows and are in increasing atomic number (not atomic mass)

• As elements move across the group (right to left) the number of valence electrons (electrons in the outer shell) increases

• Groups are the vertical columns and are groups 1 to 18

• Each element in

  a group has the same number of outer shell electrons or valence electrons

Fill in the Blanks

These atoms have the same number of orbitals, so they must be in the same

Fill in the Blanks

These atoms have similar properties, and the same number of valence electrons. This means they are all in the same
