Answer 5

React with steam (but not cold water) and acids, replacing hydrogen.
React with oxygen, forming oxides
Include Mg, Al, Mn, Zn, Cr, Fe, Cd

Question 6

Describe the activity of stable transition metals.

Answer 6

Do not react with water.
React with acids, replacing hydrogen.
React with oxygen, forming oxides
Include Co, Ni, Sn, Pb

Question 7

Describe the activity of H2 group metals

Answer 7

React with oxygen, forming oxides

Include H2, Sb, Bi, Cu, Hg

Question 8

Describe the least active metals

Answer 8

activity unreactive, forming oxides only indirectly

Include Ag, Pt, Au

Question 9

Standard reduction potential for Zn2+

Answer 9

-0.76V

Question 10

Standard reduction potential for Cu2+

Answer 10

+0.34V

Question 11

What does the activity of metals suggest?

Answer 11

The more active, the increased tendency for atoms to lose electrons and form ions
Reduction potential is smaller (or negative)

Question 12

What does the activity of nonmetals suggest?

Answer 12

The more active, the increased tendency for atoms to gain electrons and form ions
Reduction potential is greater
