Metallic Bonding

Question 1

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 2

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

Revolt · Accepted Answer

because they have flexible bonds

Question 3

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

Revolt · Accepted Answer

There are many molecular orbitals.

Question 4

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

Revolt · Accepted Answer

Cu

Question 5

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 6

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

Revolt · Accepted Answer

luster

Question 7

Which of the following metal atoms would have the highest conductivity?

Revolt · Accepted Answer

the atom with the largest radius and the most valence electrons

Question 8

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 9

Which property does a metal with a large number of free-flowing electrons most likely have?

Revolt · Accepted Answer

good conductivity

Question 10

Which combination of factors is most suitable for increasing the electrical conductivity of metals?

Revolt · Accepted Answer

more valence electrons and larger atomic radius
