In an experiment, what is the purpose of the control group?
Burka [1]

A control group is the comparison group that helps to "make sure your experiment works." A control group is separated from the rest of the experiment and nothing happens to it kinda like a controlled variable.  Controlled variables are the variables in a experiment that remains the same for example a temperature, time, type of products, etc..

Why didn't mendeleev use atomic number to arrange the elements?
Pepsi [2]

The primary reason for this was that Mendeleev didn't know that atomic numbers actually existed. Atomic numbers were only discovered a period after Mendeleev's time. The use of X-rays made it possible to find the atomic number, and those had not been discovered yet. <span>
<span>The periodic table was then arranged in 1913 by Henry Moseley in an arrangement according to atomic number.</span></span>
