What is the common element of a well designed experiment?
The common element of a well-designed experiment is a clear research question or hypothesis, a control group for comparison, random assignment of participants to groups, and proper data collection and analysis techniques.
Is polonium a element or a compound in nature?
Natural polonium exist probable as a compound (as PoPb) but this hypothesis was not surely confirmed up today.
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.
How do you verify an hypothesis in which type of liquid?
To verify a hypothesis involving a liquid, you can conduct experiments to test the hypothesis. This may involve measuring the properties or behavior of the liquid in different conditions, comparing the results with predictions based on the hypothesis. The type of liquid you choose will depend on the specific hypothesis and research question you are investigating.
Which step in the scientific method directly follows making a hypothesis?
After making a hypothesis, the next step in the scientific method is to conduct an experiment to test the hypothesis. This involves collecting data and analyzing results to determine if the hypothesis is supported or refuted.
Which describes mendeleevs use of the term ekaaluminum?
A mixture of aluminum and an unknown element.
What is the first element of the scientific method?
Hypothesis
What was the name predicted for gallium by mendeleevs?
Mendeleev predicted the name "eka-aluminium" for the element that is now known as gallium. This naming convention was based on the positions of the elements in his periodic table.
What was the problem with mendeleevs arrangement?
He pooped quite a bit
Did Mendeleevs group his elements with those of similar properties?
Yes, this affirmation is true.
What value was there in predicting the properties for gaps in Mendeleevs table?
DiscoVery of new elements
What was the problem with Mendeleevs table?
He left too many spaces between the elements......
What is the common element of a well designed experiment?
The common element of a well-designed experiment is a clear research question or hypothesis, a control group for comparison, random assignment of participants to groups, and proper data collection and analysis techniques.

What changes were made to the periodic table after Dmitri mendeleevs discovery?
they changed the 3 new Elements.
Which kind of properties fell into families or groups in Mendeleevs system of elements?
Non-metals and Metalloids
Mendeleevs periodic table was useful because it enabled scientists to predict properties of unknown?
elements
