CONCEPT

Page 4: Essential Question: How are the elements organized? THE PERIODIC TABLE

Russian chemist who first tried to classify elements based on their properties.

His table was ordered by atomic MASS (which has been changed today).

DMITRI MENDELEYEV

Page 5: Essential Question: How are the elements organized? THE PERIODIC TABLE

Chart that organizes information about the elements.

Each box contains: Chemical symbol, Atomic Mass, and Atomic Number.

Today is organized by Atomic NUMBER.

PERIODIC TABLE

Horizontal Rows on the periodic table.

Numbered 1-7.

PERIOD

Also called: FAMILY

Vertical columns on the periodic table.

Elements in same group/family have similar properties.

GROUP

Page 8: Essential Question: How are the elements organized? THE PERIODIC TABLE
