Question

how did the work of dmitri mendeleev differ from that of john newlands in the development of the periodic table? mendeleev arranged the elements according to increasing atomic mass. mendeleev predicted elements that would later be discovered. mendeleev identified elements that had similar properties. mendeleev organized elements into triads based on their properties.

Explanation:

门捷列夫不仅识别出了具有相似性质的元素，还根据元素性质的周期性规律预测了后来被发现的元素，这是他与纽兰兹工作的重要区别之一。纽兰兹提出了“八音律”，但在预测未知元素方面不如门捷列夫。

Answer:

B. Mendeleev predicted elements that would later be discovered.
