A face centered cubic cell has an edge length of 495 pm. What is that atomic radius?
1 answer:
Answer:
r = ¼a√2
Explanation:
For a face centered cubic cell, which we call FCC, the atoms at the face diagonals touch each other.
Now, If we denote the edge length of cube to be "a" and the radius of the atom is denoted as "r", as seen in the attached FCC cell:
(√2)a = 4r
Divide both sides by 4 to get;
r = ¼a√2

Explanation:
The given cell reaction is as follows.
Hence, reactions taking place at the cathode and anode are as follows.
At anode ; Oxidation-half reaction : ...... (1)
At cathode; Reduction-half reaction : ....... (2)
Hence, balance the half reactions by multiplying equation (1) by 2 and equation (2) by 3.
Therefore, net cell reaction is as follows.
Net reaction:
Thus, we can conclude that the overall cell reaction is as follows.
