What are the elements whose discovery added an entirely new row to Mendeleev's periodic table?
The discovery of gallium (Ga), scandium (Sc), and germanium (Ge) were instrumental in adding a new row to Mendeleev's periodic table because their properties helped fill in the gaps and support the periodic law at the time.
What were the three missing elements in the periodic table?
See "Mendeleev's predicted elements" in Wikipedia The answers are: scandium (Sc - 21), gallium (Ga - 31), technetium (Tc - 43), and germanium (Ge - 32) He temporarily named them to be: ekaboron (Eb), ekaaluminium (El), ekamanganese (Em), and ekasilicon (Es).
Which element would you expect to have some properties of a metal and nonmetals?
Metalloids are elements that have properties of both metals and nonmetals. They are located on the periodic table along the staircase between metals and nonmetals. Examples of metalloids include silicon, germanium, and arsenic.
One might think that FR GE and Sc might somehow be alloyed together to make this metal?
The metals FR, GE, and Sc do not naturally occur or exist. It is not possible to alloy them together to make a metal as they are not elements found on the periodic table. It is important to use actual elements when considering alloy formation.
Who created the periodic table?
The first periodic table was developed by Dmitri Mendeleev in the mid-19th century.He wasn't the only person thinking along those lines ... both John Newlands and Lothar Meyer had proposed similar ideas However, Newlands was largely criticized and ignored at the time, and Meyer didn't make any predictions, so Mendeleev's table (which did make predictions about the properties of several as-yet-undiscovered elements) is generally regarded as the first.

What elements are period 4 representative?
The period 4 representative elements are: K, Ca, Ga, Ge, As, Se, Br, Kr.
What are the characteristics of group 14 elements?
Group 14 of the periodic table of Mendeleev contain: C, Si, Ge, Sn, Pb, Fl.
Did Mendeleev create 70 elements in the periodic table?
Dmitri Mendeleev was a Russian chemist and inventor. He is credited as being the creator of the first version of the periodic table of elements.Remember the elements are found in nature, using his table he accurately predicted the properties of elements yet to be discovered. For his predicted eight elements, Mendeleev questioned some of the currently accepted atomic weights (they could be measured only with a relatively low accuracy at that time), pointing out that they did not correspond to those suggested by his Periodic Law. He noted that tellurium has a higher atomic weight than iodine, but he placed them in the right order. He was puzzled about where to put the known lanthanides, and predicted the existence of another row to the table. Some people dismissed Mendeleev for predicting that there would be more elements, but he was proven to be correct when Ga (gallium) and Ge (germanium) were found in 1875 and 1886 respectively, fitting perfectly into the two missing spaces.
What were the three missing elements in the periodic table?

What elements begin with g?
4Gallium (Ga)Germanium (Ge)Gadolinium (Gd)Gold (Au)
What element did mendeleev call ekasilicon?
Mendeleev proposed that there must be missing elements, to which he gave the provisional names Ekaboron, Ekaaluminum and Ekasilicon. Scankium, Gallium and Germanpoop were discovered in 1879, 1875 and 1886, respectively, with properties very close to those predicted by Mendeleev. hey Glen
What prediction did Mendeleev make that came true less than 20 years?
He said that te three new elements would be discovered, and he described their properties.
