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 was the first periodic table?
Hydrogen is the first chemical element in the Periodic Table of Mendeleev.
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 are the two factors that led to widespread acceptance of Mendeleev's periodic table?
The two main factors that led to the widespread acceptance of Mendeleev's periodic table were its accurate prediction of the properties of then-unknown elements and its ability to explain the periodic trends observed in elements. Additionally, Mendeleev's table was able to organize the known elements in a logical and systematic manner, making it easier to understand and use.
What physical property did Mendeleev use to places the element in rows on the periodic table?
Mendeleev used the increasing atomic mass of elements to arrange them in rows on the periodic table. This allowed for elements with similar properties to be grouped together and for the gaps to be left for undiscovered elements.
What method did Mendeleev use to organize the periodic table of elements?
An element's atomic number, or how many protons it has.
What did Mendeleev do when he discovered a new element?
To celebrate, he cracked open a bottle of vodka. Just kidding, actually, he didn't discover any elements, he just figured out a way to organize them according to their chemical properties. We still use his method today.
What method did Dmitri use to organize the elements of the periodic table?
Dmitiri Mendeleev arranged the Periodic Table of elements in order of increasing atomic masses.
Why did Mendeleev want to make a periodic table of the of the element?
Mendeleev was working on a text book to use with his students.
Which describes Mendeleev's use of the term aluminum?
A mixture of aluminum and an unknown element.
What is a tool scientist use to organize the elements and to the between their chemical properties?
Probable you think to the periodic table of Mendeleev.

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 was the first periodic table?
Hydrogen is the first chemical element in the Periodic Table of Mendeleev.
The orderly method that scientists use to solve problems is called?
The orderly method that scientists use to solve problems is called the scientific method. This helps to organize thoughts and procedures.
Which property did Mendeleev primarily use to classify the element?
Mendeleev primarily used the element's atomic mass to classify them. He organized the elements into a periodic table based on their increasing atomic mass, allowing him to predict the properties of missing elements and arrange them in a logical order.
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.
Scientists use to organize questions and reach conclusions that are backed by scientific evidence and research?
the Scientific Method
