Dmitri Mendeleev was a Russian chemist who proposed the Periodic Law. He published the first Periodic Table of the chemical elements in 1869, based on the increasing atomic masses of the different elements.

Which of the fllowing is not a required element of preparing a proposal estimate?
A detailed summary of project objectives and outcomes is not typically a required element of preparing a proposal estimate. The estimate usually focuses on the costs associated with completing the project, such as labor, materials, and overhead expenses.
What proposal offers solutions to a problem or improvement to a solution?
A solution proposal typically presents a clear description of the problem, offers specific solutions or improvements to address the problem, and outlines the anticipated benefits or outcomes of implementing the proposed solutions. It should also include a detailed action plan and resources required for execution.
What makes up the halogen triad?
This refers to an old "history of science " topic around the work done prior to mendeleevs on Periodic Table. Elements were put in triads with similar properties. The halogen triad was chlorine, bromine and iodine. Pretty useless idea long term but a good start for people who came later.
Mendeleevs periodic table of elements was created in 1901?
Actually, Dmitri Mendeleev formulated the periodic law and published his periodic table of elements in 1869. This table arranged elements by increasing atomic mass and grouped them based on similar properties, predicting the properties of missing elements. It was a significant contribution to the field of chemistry.
How did chemist change mendeleevs perioic table in the early 1900s?
Chemists in the early 1900s made changes to Mendeleev's periodic table by rearranging elements based on their atomic number instead of atomic mass, leading to the development of the modern periodic table. This change accurately emphasized the relationship between an element's properties and its atomic number, rather than its atomic mass, and helped to better organize the elements.
What was the problem with mendeleevs arrangement?
He pooped quite a bit
What was the problem with Mendeleevs table?
He left too many spaces between the elements......
What value was there in predicting the properties for gaps in Mendeleevs table?
DiscoVery of new elements
Did Mendeleevs group his elements with those of similar properties?
Yes, this affirmation is true.
What changes were made to the periodic table after Dmitri mendeleevs discovery?
they changed the 3 new Elements.
Mendeleevs periodic table was useful because it enabled scientists to predict properties of unknown?
elements
Which kind of properties fell into families or groups in Mendeleevs system of elements?
Non-metals and Metalloids
Difference between project proposal and research proposal?
The difference between a research proposal and a project proposal is that a research proposal may lead to a project proposal eventually. A research proposal involves a plan for learning about something, a project proposal involves money for doing something.
Was Mendeleevs table a completely regular grid?
not if u mean completely filled in but square by square yes
Which matches Mendeleevs prediction for the properties of eka-aluminum?
It would be a soft metal with a low melting point.
What is the difference between academic research proposal and a project proposal?
The difference between a research proposal and a project proposal is that a research proposal may lead to a project proposal eventually. A research proposal involves a plan for learning about something, a project proposal involves money for doing something.
Is proposal adverb?
No, the word "proposal" is not an adverb.The word "proposal" is a noun.
