How did Dmitri Mendeleev arrange his version of the periodic table?

• Increasing atomic number

• Increasing atomic mass

• Decreasing atomic number

• Decreasing atomic mass

On the modern periodic table, groups/families are ​ (a)   ​ (b)   and periods are ​ (c)   ​ (d)   .

• vertical
• columns
• horizontal
• rows
• Diagonal
• upside down
• racks

Due to elements in the same group/family having the same number of valence electrons, they will have the same:

• chemical properties

• color

• atomic number

• electrons
