Metallic Bonding

Question 1

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.

Question 2

Which statement is true when a crystal is formed from many metal atoms?

Revolt · Accepted Answer

There are many molecular orbitals.

Question 3

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 4

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

Revolt · Accepted Answer

Cu

Question 5

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

Revolt · Accepted Answer

band theory

Question 6

Which is a characteristic of the electron sea model for metallic bonding?

Revolt · Accepted Answer

Electrons flow easily between metal nuclei.

Question 7

Which characteristics of metal atoms help explain why valence electrons in a metal are delocalized?

Revolt · Accepted Answer

Metal atoms are large and have low electronegativities.

Question 8

Which property is true for metals?

Revolt · Accepted Answer

low ionization energies

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 property is better explained by the band theory than by the sea-of-electrons model?

Revolt · Accepted Answer

luster
