Question

Answer

For Dobereiner's triads the atomic weight of middle term is almost average of other two I. e a+c/2=b where a, b, c are atomic weight of the element....thus law of triad is applicable to cl,br,I..
..

Answer

Law of Triads is a classification system proposed by a German scientist, Johann Dobereiner in 1829. According to this law, the elements with similar chemical and physical properties occur in groups of three called triads. The atomic weight of the middle element of a triad is nearly the average of the other two elements. Let's see which set of elements follows the Law of Triads.

Option A: Sodium, Potassium, Rubidium
- These elements are placed in the same group (Group 1) of the periodic table.
- However, the atomic weight of the middle element (Potassium) is not nearly the average of the other two elements.
- Therefore, this set of elements does not follow the Law of Triads.

Option B: Fluorine, Iodine, Bromine
- These elements belong to the same group (Group 17) of the periodic table.
- The atomic weight of the middle element (Iodine) is nearly the average of the other two elements.
- However, these elements do not have similar chemical and physical properties.
- Therefore, this set of elements does not follow the Law of Triads.

Option C: Chlorine, Bromine, Iodine
- These elements belong to the same group (Group 17) of the periodic table.
- The atomic weight of the middle element (Bromine) is nearly the average of the other two elements.
- These elements have similar chemical and physical properties.
- Therefore, this set of elements follows the Law of Triads.

Option D: Lithium, Beryllium, Boron
- These elements belong to different groups of the periodic table.
- Therefore, this set of elements does not follow the Law of Triads.

Hence, the correct option is C. Chlorine, Bromine, and Iodine follow the Law of Triads.

Answer

Option c

Answer

It is also the example of law of traids

Answer

Ans c triads ke liye middle bale atom pass bale atom ka average hota cl ka 35.5 ,br ka 80 ,l 127 br cl or I ja average hai

Answer

Law of Triads is applicable to Chlorine, Bromine, and Iodine.

Answer

Triads should obey (a+c)/2 = b where a, b, c are at.weights of elements whose order will be a, b, c.

Answer

The average of lithium and boron gives beryllium. so y can't this also be the ans

Answer

C option is correct

1) Cl=35.5

2)I=127

3)Br=80

Acc, to law of traids, mass of Br should be equal to average mass of Cl and I

(Cl + I) / 2 =( 35.5 + 127)/2 =162.5/2=81.25

This is almost equal to 80 which is the mass of Br. Hence it is correct

Answer

How is it possible?

Answer

Law of traits m btaya tha ki jo three elements de rkhe h unme s first and third k mass ki add krke 2 s divide kr do fir jo bhi answer aae use bche hue element yani ki second element s match ki agr vo same to to un dino element m law of trait follow ho rha h otherwise nhi ho rha bsss simpleeeee
