Best answer


Dobereiner’slaw of triads: When elements are arranged in order of increasing atomic masses,groups of three elements (triads),having similar chemical properties are obtained. The atomic mass of the middle elements of the triad being equal to the arithmetic mean of the atomic masses of the other two elements.

  • What do you mean by law of triad?

  • According to the law of triads, when elements are arranged in increasing order of their atomic masses, the arithmetic mean of the atomic masses of the first and third element in a triad is approximately equal to the atomic mass of the second element in that triad. Question 2: What do you mean by triad in reference to Dobereiner triads?

  • What is Dobereiner’s law of triads?

  • Dobereiner’s law of triads also stated that the atomic masses of the first and third elements in the triad would be approximately equal to the atomic mass of the second element in the triad. Also, he suggested that this particular law could be extended for the other quantifiable properties of elements such as density.

  • What is a triad of elements?

  • He observed that groups of three elements (triads) could be formed in which all the elements shared similar physical and chemical properties.

  • Can Dobereiner鈥檚 triads group elements according to their properties?

  • Although Dobereiner鈥檚 triads could not group all elements according to their properties it said the foundation for the formation of the modern periodic table. Question 1: What is the law of triads?

  • What is the discovery of periodic law?

  • Discovery of Periodic Law. In particular, contributions made by Lothar Meyer and Dmitri Mendeleev made trends in element properties apparent. They independently proposed Periodic Law in 1869. The periodic table arranged the elements to reflect Periodic Law, even though scientists at the time had no explanation for why properties followed a trend.

  • How does periodic law relate to the periodic table?

  • Understand How Periodic Law Relates to the Table. The Periodic Law states that the physical and chemical properties of the elements recur in a systematic and predictable way when the elements are arranged in order of increasing atomic number. Many of the properties recur at intervals. When the elements are arranged correctly,…

  • Who is the father of Modern Periodic Law?

  • Who gave the modern periodic law? In 1869, Dmitri Mendeleev and Lothar Meyer established the periodic law independently. The first periodic table was developed by Mendeleev and soon followed by Meyer.

  • How did the periodic law make people more curious about chemistry?

  • After knowing the periodic law, chemists noticed that there is an analogy between the 94 naturally occurring chemical elements. This analogy made people more curious about the chemistry of these elements. Scientists made various artificial elements.
