Question 3

Which is the best metal to use in an alloy to increase its electrical conductivity?

Revolt · Accepted Answer

Cu

Question 4

In a piece of metal, what holds the atoms together?

Revolt · Accepted Answer

the positive charges of the nuclei and the negative charges of delocalized electrons

Question 5

What is another name for the molecular orbital theory of bonding in metals?

Revolt · Accepted Answer

band theory

Question 6

Which statement best describes the basis of the band theory of metallic bonding?

Revolt · Accepted Answer

Atomic orbitals overlap to form molecular orbitals in which the valence electrons of the atoms travel.

Electrons flow easily between metal nuclei.

Question 9

Which is most likely the result of millions of metal atoms crowding together so that molecular orbitals become combined?

Revolt · Accepted Answer

the formation of bands in a crystal

Question 10

Which reason best explains why metals are ductile instead of brittle?

Revolt · Accepted Answer
