The atoms along the staircase are called 

• metals
• nonmetals
• metalloids
• noble gases

• true
• false

NGSS.HS-PS1-1

NGSS.HS-PS1-2

Valence electrons are: 

• Electrons farthest away from the nucleus
• Electrons closest to the nucleus
• Electrons that just come and go - they don't stay with the atom

The groups on the periodic table tell you 

• the number of electron shells
• the number of valence electrons
• the number of electrons
• the number of protons

What is the relationship between the families in each column?

• Their number of electron shells give them similar physical and chemical characteristics.
• They are always combustible.
• None of them can bond.
• Their number of valence electrons give them similar physical and chemical characterstics

There are 92 elements that are found naturally on Earth.  The rest are

• unnatural
• found on Mars
• uncommon
• synthetic

Which element has similar characteristics to Neon?

• Argon (Ar)

• Chlorine (Cl)

• Florine (F)

• Oxygen

** In order for an atom to become stable (that means it can't bond any more), in most cases the atom needs ________ valence electrons.

• 8

• 6

• 4

• 2

Mendeleev first ordered the periodic table of elements by increasing

• atomic number

• atomic mass

• atomic symbol

• atomic weight
