Answer:
d
Explanation:
triad: A triad is a group of 3 elements where the sum and average of the atomic weight of 2 elements is equal to the atomic weight of the middle one
the atomic weight of Li is 6
the atomic weight of k is 38
- average = 38+ 6 ÷2
- = 22
- which is the atomic weight of Na
similarly, (b) and (c) also follows the traid
therefore(d) is not the triad
