♡CORRECT ANSWER WILL BE MARK AS BRAINLIST !♡

Find the maximum Dobereiner's triads from Newlands' Octave.(Prove with calculations.)​

Answer 1

Answer:

yes, dobereiner's triads also exist in the columns of newlands ' classification of elements based on the law of octaves.consider the elements lithium (Li),sodium (Na) and potassium (k).which are present in the second column of newlands' classification of elements .now if we start with lithium as the 1st elements,then the 8th elements from it is sodium should be similar to those of the first elements lithium.again, if we take sodium as the 1st elements,then the 8th elements potassium should be similar to those of the 1st elements sodium.this means that according to newland's law of octaves,the elements lithium,sodium and potassium should have similar chemical properties.we also know that lithium ,sodium and potassium form a dobereiner's triad having similar chemical properties .from this we conclude that dobereiner's triads also exist in the column's of newlands octaves.
