Question

Which statement explains why a strip of silver is a better electrical conductor

than a strip of silicon?
A. Silicon atoms have a much larger atomic mass than silver atoms.
B. Silver atoms share their outer electrons much more freely than
silicon atoms do.
C. Silver atoms have a much larger atomic mass than silicon atoms.
D. Silicon atoms share their outer electrons much more freely than
silver atoms do.

Answer 1

20

Step-by-step explanation:

The number of protons in an atom equals the atomic number, and the total of the number of protons and neutrons equal the atomic mass.

19th atomic number

As a result, the number of protons (p) equals 19.

The atomic mass is 39.

The total number of neutons (n)

= (n + p) - (n + p)

= 39 minus 19

20 %

Step-by-step explanation:

As a result, the total number of neutrons and protons (n + p) equals 39.

Answer 2

Silver atoms share their outer electrons much more freely than

silicon atoms do.

Step-by-step explanation:

Metals are known to share their outer electrons readily. For this reason metals are known to be electro positive.

Metals are good conductors of electricity because they share their outer electrons readily.

Silver is a metal and silicon is not a metal hence silver is a better electrical conductor

than a strip of silicon because Silver atoms share their outer electrons much more freely than silicon atoms do.
