aaccording to dobereiner s law of trades ;
when element are arranged in group of 3 elements with increasing atomic mass the atomic mass of middle element is equal to the Arithmetic mean of atomic mass of other two
_____

Answer 2

When the elements are grouped in groups of three in the same order of increasing atomic mass, he discovered that the atomic mass of the element in the middle is the arithmetic mean of the other two. He created the 'Triad' by arranging three elements in a single group in this manner. Dobereiner's Triads is the name given to this particular arrangement of parts.

Explanation:

• Dobereiner triads are defined in chemistry as any of various sets of three chemically identical elements, one of which has an atomic weight that is roughly equal to the mean of the atomic weights of the other two.
• Calcium-strontium-barium triads, as well as sulfur-selenium-tellurium triads, are examples of such triads.
• Between 1817 and 1829, the German chemist J.W. Döbereiner discovered chlorine, bromine, and iodine.
• The atomic-weight classification of these elements began with this triad. Johann Wolfgang Dobereiner, a German scientist, developed Dobereiner triads, which are groups of elements with identical properties.
• The atomic masses of the first and third elements in the triad would be about equal to the atomic mass of the second element in the triad, according to Dobereiner's law of triads.
• He also proposed that this law be extended to include other quantitative qualities of elements, such as density. A German scientist named Johann Wolfgang Dobereiner made an effort.
• It's regarded to be one of the first attempts to classify elements.
• Metals and nonmetals were divided into two categories in the first classification.
• Some elements, such as boron, exhibited features of both metals and non-metals, making classification difficult.
• When the elements are grouped in groups of three in the same order of increasing atomic mass, he discovered that the atomic mass of the element in the middle is the arithmetic mean of the other two.
• He created the 'Triad' by arranging three elements in a single group in this manner.
• Dobereiner's Triads is the name given to this particular arrangement of parts.
