In his version of the periodic table, Mendeleev based his arrangement of the elements on an element's

• atomic number

• chemical symbol

• name

• atomic mass

The order of elements in the modern periodic table is based on an element's

• atomic number

• chemical symbol

• name

• atomic mass

Elements within the same group in the periodic table have similar properties because they have the same number of

• protons

• neutrons

• ions

• valence electrons

Ionization refers to the process of

• changing from one period to another

• losing or gaining protons

• turning lithium into fluorine

• losing or gaining electrons

What does the 6 represent?

• atomic mass
