It is a gas
It is a solid
31

columns
33
The first Periodic Table was created by:
Dmitri Mendeleev
Henry Mosely
Amadeo Avogadro
Ernest Rutherford
34
Periodic Trends:
The size of an atom tends to
increase as you go across a period
increase as you go down a group
decrease as you go across a period
decrease as you go down a group
35
Why do the periodic trends increase/decrease from right to left across the periodic table?
# of energy levels increases to the right, so electrons are further out
# of protons increases to the right, so electrons are pulled more tightly
# of energy levels decreases to the right, so electrons are closer in
# of protons decreases to the right, so electrons are pulled less tightly
36
Why did Mendeleev organize his Periodic Table by Atomic Mass Rather than Number?
Atomic Mass is more closely related to reactivity
Protons had yet to be discovered
Atomic Mass is independent of chemical reactions
Its the Mendeleevian way

Atomic weight
Atomic number
