What else can I help you with?
A Russian chemist named Dmitri Mendeleev organized elements by?
Mostly by atomic mass, but in some cases by (educated) guess where he thought the measured atomic masses weren't correct.
When was gallium discovered and by who?
In 1871, the gallium was dicoversd by a Russian chemist Dmitri Mendeleev, who named it "eka-aluminium" on the basis of its position in his periodic table..
Who developed the original periodic table?
The first periodic table was developed by a Russian chemist and inventor named Dmitri Mendeleev, who arranged the elements by atomic mass. However, British chemist Henry Moseley later decided to order the elements by atomic number, thus creating a new arrangement. Moseley's table is the one used today.
Whatever happened to the guy that played Mickey on Equalizer?
His acting resume is extensive, appearing in numerous television programs including Profit, The X-Files, Star Trek: Voyager, Charmed, 24, Max Steel, The Inside, Law & Order and Babylon 5, but he is best known for his role as Mickey Kostmayer in the 1980s hit show The Equalizer, as well as for his recurring role as vampire hunter Daniel Holtz in the cult series Angel, the spin-off from Buffy the Vampire Slayer. He played the lead role in Stephen King's Golden Years. Szarabajka has also contributed his voice to several audio books, notably "Fierce Invalids Home from Hot Climates" by Tom Robbins, for which he won the 2001 Audie Award for Best Fiction, unabridged,Fear Nothing and Seize the Night by Dean Koontz, and Rising Sun, by Michael Crichton. Additionally, he provided the voice for antagonist Dmitri Yuriev in the Xenosagaseries and for Emile Dufraisne in Tom Clancy's Splinter Cell: Double Agent. Most recently, he played the role of Detective Stephens in the Batman Begins sequel "The Dark Knight" and voiced Dr.Terrence Kyne for the animated sci-fi horror movie Dead Space: Downfall based out of the Dead Space video game.
Who is idea was it to arrange the elements in the periodic table according to their chemical and physical properties?
Dmitri Mendeleev
Who arrange the elements according to atomic mass and use the arrangement to predict the properties of missing elements?
Dmitri Mendeleev
Who arrange the periodic table in elements?
The Russian, Dmitri Mendeleev's periodic table became available to the scientific community vi publication in 1869 and he is generally credited with its "creation"
The first person to arrange elements in a table?
Dmitri Mendeleev
How did this Russian scientist first arrange the elements?
Dmitri Mendeleev arranged the elements in his periodic table based on their atomic masses and chemical properties. He left gaps for undiscovered elements and predicted their properties accurately.
Who arranged the elements by atomic mass and used it to predict properties of missing elements?
Independently by Dmitri Mendeleev and Lothar Meyer in 1869
What is the contrribution of Dmitri mendeleev?
Dmitri mendeleev arranged elements in order of increasing atomic masses. He considered chemical properties of the elements, their oxides and nitrides.
Scientist that first arranged and classfied elements into a chart?
Dmitri Mendeleev is the scientist who is credited with first arranging and classifying elements into a chart that laid the foundation for the modern periodic table. Mendeleev's periodic table arranged elements by their atomic weight and predicted the properties of unknown elements that were yet to be discovered.
Who is knownas the fatherof the periodic table?
Dmitri Mendeleev is known as the father of the periodic table. He is credited with creating the first widely recognized version of the periodic table in 1869 based on the patterns he observed in the properties of elements.
How did Dmitri Menedeleyev arrange elements on his first periodic table?
Dmitri Mendeleev arranged elements on his first periodic table by increasing atomic mass and grouping elements with similar properties together. He left gaps for missing elements and predicted the properties of these undiscovered elements based on their position in the table.
Who determined that the properties in elements are periodic?
The Russian chemist Dmitri Mendeleev.
What two elements did Dmitri Mendeleev switch?
Dmitri Mendeleev switched the positions of iodine and tellurium in his periodic table based on their properties, correctly predicting the existence and properties of missing elements.
