How did Mendeleev place germanium on the periodic table?
Mendeleev was able to predict the properties of the yet unknown element (Germanium) by the properties of the surrounding known elements on his periodic table of the elements. Predicting properties such as reactivity, density, atomic mass, etc., he knew where the undiscovered element would be placed.
Why did Mendeleev leave a space for the unknown at the time element germanium in his periodic table?
Well, honey, Mendeleev left a space for germanium because he was a smart cookie who knew there was something missing in his periodic table. Turns out, germanium was later discovered and filled that gap, proving Mendeleev's intuition was spot on. So, he left that space like a boss, knowing someone would eventually fill it in.
Periodic table what was missing at first?
When the periodic table was first created by Dmitri Mendeleev in 1869, there were some gaps or missing elements that had not yet been discovered. Mendeleev left spaces in his table for these unknown elements, accurately predicting both their properties and where they would be located in the table once they were discovered. Over time, these missing elements, such as gallium and germanium, were discovered and filled in the gaps as Mendeleev had predicted.
What scientist also proposed a periodic table about the same time as dimitri mendeleev?
Unknown to Mendeleev, Lothar Meyer was also working on a periodic table. Although his work was published in 1864, and was done independently of Mendeleev, few historians regard him as an equal co-creator of the periodic table.
When Mendeleev changed the lay out there were gaps how did the gaps help scientists looking for undiscovered element?
The gaps in Mendeleev's periodic table allowed scientists to predict the properties of unknown elements that should fill those positions based on the trends observed in the table. This guided their search for these undiscovered elements by providing a roadmap to their characteristics. This led to the discovery of new elements such as gallium, germanium, and scandium.

What describes Mendeleev and use of the term Eka aluminum?
Dmitri Mendeleev was a Russian chemist who created the periodic table. The term "Eka aluminum" refers to the element gallium, which he predicted would exist based on gaps in the periodic table and similarities with aluminum. Mendeleev's predictions were accurate and gallium was discovered later.
What describes mendeleev use of the term eka-aluminum?
Mendeleev used the term "eka-aluminum" to predict the properties of an undiscovered element that would have similar characteristics to aluminum. This was part of his periodic table where he left gaps for undiscovered elements. Eka-aluminum was later discovered and named gallium, confirming Mendeleev's periodic trends.
What is the modern name for eka-silicon?
Ekasilicon is germanium['eka' is Sanskrit language for: 'first' place down under Si)Germanium was isolated in 1886, and provided the best confirmed prediction of Mendeleev's periodic table, which was built up before the discovery of Ge.(Professor Dmitri Mendeleev published the first Periodic Table of the Atomic Elements in 1869).When he proposed his periodic table, he noted some gaps in the table, and predicted that as-of-yet unknown elements existed with properties appropriate to fill those gaps.
What are the unknown elements of Mendeleev's Lab of 1869?
Oh, dude, Mendeleev's Lab of 1869 was like the OG chemistry party. The unknown elements back then were basically like the missing guests who RSVP'd but never showed up. It's like trying to throw a surprise party for hydrogen and helium, but they ghost you and leave you with a bunch of uninvited elements crashing your periodic table bash.

Why were the elements Ga Sc and Ge important to Mendeleev?
Mendeleev included gallium (Ga), scandium (Sc), and germanium (Ge) in his periodic table because they filled gaps in the sequence of known elements at the time and helped demonstrate the periodicity of their properties. These elements were crucial in showing the predictive power of Mendeleev's periodic table in suggesting the existence of unknown elements and their properties.
What scientists also proposed a periodic table about the same time as Mendeleev?
Unknown to Mendeleev, Lothar Meyer was also working on a Periodic Table. Although his work was published in 1864, and was done independently of Mendeleev, few historians regard him as an equal co-creator of the periodic table.
Which describes Mendeleev's use of the term aluminum?
A mixture of aluminum and an unknown element.

What value was there in predicting the properties for gaps in Mendeleev and table?
DiscoVery of new elements
