By making this small adjustment, the patterns that didn't work for Mendeleev's design were corrected in Moseley's table. Henry Moseley, a British chemist, reordered the Periodic Table by increasing atomic number instead of atomic mass. In 1913, the final touch was made to the Periodic Table we currently use today. Later, Scandium and Germanium were also discovered and fit just where he had predicted. Gallium possessed many of the same properties that Mendeleev had predicted, and seemed to fit perfectly where he said it would. What makes an element reactive Number of valence. Skeptics didn't take this new table seriously until the element Gallium was discovered in 1875. Reactivity is a chemical property that determines how elements will react with others to form compounds. Mendeleev left holes in the table where he couldn't find an element to fit into a pattern, but he predicted the characteristics of these elements. Organizing these cards into groups based on their properties allowed him to see that there were indeed patterns that fit in vertical columns when the elements were ordered by increasing atomic weight. He wrote down each of the 63 known elements on a card, along with their physical and chemical properties. In 1869, Dmitri Mendeleev, a Russian chemist and playing card fanatic, revolutionized the Periodic Table as we know it.

Unfortunately, there were not enough patterns that fit with Newlands' Periodic Table, so there was still work to do.

When he presented his theory to the England Chemical Society, he was laughed at. He noticed that every 8th element was similar to the one that came next, and called this, The Law of Octaves. In 1865, John Newlands sorted the growing number of elements based on increasing weight by metals and non-metals. In 1829, Johann Wolfgang Dobereiner grouped the known elements into families of "triads" based on similar properties.
