We can say, they have same valence electrons, i.e 2 electrons.
The properties of alloys most resemble metal. Copper, tin, fiberglass.
Answer:
Option (B) 3.
Explanation:
In the model represented above, the two extreme represent carbon atoms since no other group are attached to it. The joint at the middle also represent carbon atom.
Thus, we can write a more simplify illustration for the model above as
C—C—C
From the above illustration, we can see that the model contains 3 carbon atom.
The third one
